Published on November 14, 2018 by

MIT grad shows how to solve for the sides and angles of a right triangle using trig functions and how to find the missing sides of a right triangle with trigonometry basics. To skip ahead: 1) For HOW to CHOOSE A TRIG FUNCTION to solve for a side you don't know, skip to time 2:10. 2) For how to SOLVE for the LAST SIDE with TRIG, skip to time 6:18. 3) For how to SOLVE for the LAST SIDE with the PYTHAGOREAN THEOREM, skip to time 8:41. 4) For how to SOLVE FOR THE LAST ANGLE, skip to time 10:38. For my video that introduces the BASIC TRIG functions (sin, cos, tan, csc, sec, and cot) and SOH-CAH-TOA, jump to: https://youtu.be/bSM7RNSbWhM Nancy formerly of MathBFF explains the steps.

HOW TO SOLVE A RIGHT TRIANGLE: If you have to "solve a right triangle," it just means to find all the missing angles and sides of a triangle. When you have a right triangle and you already know at least one of the angles (other than the right angle) and at least one of the sides, you can solve for the other sides using a trig function: sine, cosine, or tangent. When solving right triangles, you can use the memory trick sohcahtoa (SOH CAH TOA) to remember the trig ratios for sin, cos, and tan. Pick the trig function that includes both the side you already know AND the side you're looking for. You can use algebra to solve for the length of the unknown side, to find the missing side of a triangle. Once you have that side, you have two options for finding the last unknown side. You can either: 1) use another trig function, or 2) use the Pythagorean Theorem formula. Then you will have all the sides. Make sure you have found all the angles inside the triangle so that you've really "solved" the whole triangle. If you know two angles already (one of them is the right angle, 90 degrees), you can find the last unknown angles really quickly. Since all three angles have to add up to 180 degrees, you can subtract the two angles from 180 to find the unknown angle in degrees.

For how to identify adjacent, opposite, and hypotenuse sides of a triangle, and for an introduction to the trigonometric functions sin, cos, and tan, jump to my BASIC TRIGONOMETRY intro video: https://youtu.be/bSM7RNSbWhM

  • James Parlane 4 years ago

    I have this brilliant idea. How about saying the two other angles must add to 90. Forget the right angle. The only part you really need is tan if you need to find out how high a tree is. walk back 10 metres, get the angle between you and the top of the tree, tan of that times 10 minus one because you are measuring 1 m. from the ground is the height of the tree. Once upon a time here in nz. there was a navigator who did not know how high a mountain was because he did not look at a map or chart as they call it. He programmed the auto pilot to fly but did not check his angles and it was a case of plane plus mountain equals minus 257 people. Perhaps he should have listen3d to wolfman Jack when he said ‘baby if you have the curves, I have the angles’?

    Excellent run down. As a builder years ago I taught myself Trig to do more tricks with fancy roof rafters etc. That took me a couple of weeks to do what you did in 14 minutes.

    • Paul Jenkins 3 years ago

      But Bravo, Nancy had to spend years in college to learn how to do Trig and other topics in advanced mathematics. It didn’t happen overnight. I’m sure Nancy is an intelligent woman, but she was not born with a BS degree in Mathematics.

  • BobC 4 years ago

    Well, I was away for a while and missed several videos. I spent the first half of this year as a full-time volunteer algebra tutor at a local “continuation” high school, for students who weren’t well-served by the regular system. All had failed algebra at least once, and most had failed entire years of school. Many had severe life stresses outside of school, with family, poverty and various drug dependencies and mental health issues. A number of them had jobs, and many were on the verge of aging out of the system.

    The first thing I learned is that, despite being a master of algebra, I didn’t know a thing about teaching it. So, immersion in pedagogy was an initial task.

    The second thing I learned was that being able to teach algebra wouldn’t magically enable these students to learn it. Most weren’t in a state of mind or heart that was conducive to learning anything, much less something as abstract as algebra. The vast majority believed they had no math abilities, and the rest believed algebra had no practical role in their lives.

    With all this stacked against them, they then had to contend with the intense frustration and self-imposed humiliation they felt when they couldn’t do a review problem they had been able to solve a year previously.

    The third thing I learned was that I had to start with these students where they actually were, and not where I thought or hoped they would be. That meant asking if they had slept the night before. Had eaten breakfast. Weren’t too hot or cold. Felt well. Were hydrated. Weren’t (too) high.

    The fourth thing I learned was that to find out where they were I had to become a powerful observer, a gentle questioner, a rock-solid presence for them, and find ways to create a space of safety and careful risk-taking.

    I had to do lots of work on myself. To learn to get close to students without going over the edge. To “love them to death” as one teacher put it to me, without killing myself. To be totally warm and open, yet keep a safe distance.

    I didn’t have nearly enough successes, but damn if I didn’t have some awesome ones! I remember one young woman who would do this low “Ohhhh” when she “got” something, and I remember watching her take a test where she did that twice, during the test!

    There was a very sullen young man who was always high (and a genuine ass of the first order), but who somehow agreed to come in straight enough to give algebra a serious try. He couldn’t do any of the review problems, so I grabbed the prior text and went through it backwards. We got to the point where we found his problem was multiplication: He had forgotten how it worked, and had never memorized any multiplication tables. We started from there and made slow but steady progress. One day walking across the quad between classes, I saw him on the far side: He changed direction to come past me for a fist-bump. Two of his other teachers were also there and were shocked, nearly to the point of tears (as was I). It was the first time any of us had seen him have a positive self-directed interaction with any adult on campus!

    There were more victories like that, large and small.

    Then my savings started to run low, and I had to get another day job as a senior systems engineer. It’s a great job, with a talented team working on cool products. But I find I’m in a bizarre state: I’ve never had a job I liked more and loved less.

    Because my heart isn’t in it: What I want to do is teach! So I’m living on a fraction of my salary, saving money for tuition for my teaching credential, saving money to pay off my mortgage, and saving money so I can afford to live on teacher’s pay in Southern California.

    To tell you the truth, the students who “get it” I’ll turn over to you: They won’t need me for much, and you’ve got that ASMR thing going. I want to work with students who think they have an allergy to math combined with existential dread and nightmares.

    • ccsvenezuela2006 3 years ago

      Beautiful experience. You are right, the first thing to tackle is their fear of math. When we get to high school we are told “you’re going to see algebra uuuh” as if it were a demon. And then in university it is “calculus oooh so difficult”. But we all have a brain capable of math. I blame said fear and the people that don’t know how to teach, who just make students feel worse. Congratulations.

    You have that Susanna Hoff’s look, lead singer for the ‘Bangles’. You know the tune… ‘Eternal Flame’. Quite pleasing to the eye ! With respect to ‘Theta’, I find its use outside of Math interesting, in that it plays a major part in Hypnosis (being the vibrational frequency of the programmable state) or Hyp-Gnosis as I like to spell it Hypnosis even uses the ‘term’…being ‘Triggered’ ! So there seems to be a clear connection to Trigonometry or as I like to refer to it as Trigger-nometry ! I do enjoy recreational Math, kind of gets me into the mind-set for that old TV program of NUMB3RS where the number ‘3’ becomes distinctly recognizable…an Old Wizard

      Hasn’t MGTOW taught you anything about women? Flagrantly complimenting beautiful women that you do not know and have never met does not turn them into kind, loving, and caring women, nor will they send their love to you in return. It spoils them and has the opposite effect. The more you show them how much you love, care about, or appreciate them, the more apathetic they become towards you, unless the two of you have already established that there is good chemistry between you. Do yourself and all other men a favor and stop building her massive ego. 🙂

    I was building some cold frames to overwinter plants and used right-triangle trigonometry a couple years ago. To the side, cold frames are basically a square or rectangle below a right triangle. Using these equations, the measurements were accurate down to 1/32″, basically as accurate as the tape measure could go. Very practical in building projects.

    • Paul Jenkins 2 years ago

      @Sami Khan listen to you… You really can’t handle the truth. Many of these creeps, like you, are, in fact, infatuated with Nancy. Just can’t take your eyes off of her, right. Maybe, if you write Nancy a love song, she will fall in love with you. What do you think? Here, let me start a song for you…

      Well I’m beginning to think
      That man has never found
      The words that would make you want me
      That had the right amount of letters
      Just the right sound
      That would make you hear
      Make you see that you are driving me out of my mind…

      Now, you finish the song…

      Sing that song to Nancy and watch her melt into a sensual puddle of Differential Equations and advanced Calculus.

      LOL!

    • Paul Jenkins 2 years ago

      @Akansha Pantyou’re a young, pretty girl; help Sami Khan build up his self-esteem so he can ask Nancy out for a romantic date. Maybe if you spend some time with Sami, he will fall in love with you. Then you can help rid him of his creepy behavior.

    • Sami Khan 2 years ago

      @Paul Jenkins Dude do you realize youre the one who commented the creepy stuff right… whyre you trying to turn it on meXD get a life dude. Proofs in the comments. Read

    • Paul Jenkins 2 years ago

      @Sami Khan factual info is not creepy. You are creepy because of the pathetic narrative you have chosen to follow and how you keep stalking me. The fact is, you are not intelligent enough to understand why sending love and affection to a woman who is not interested in you is, in fact, not a good idea. But I do teach a Woman 101 class. It is $100 per hour and lasts for two weeks. Let me know when you are ready and I will schedule the class for you. As for payment, I prefer cash up front. Just saying…

Hopefully, you will not waste your time and hers by giving her yet another sensual compliment on her beauty. She will, of course, not read it, not respond, and not care one iota about all these compliments. But as a whole, she may enjoy the attention, but only to a certain point.

    • Paul Jenkins 3 years ago

      @paola f. yes, I know you are a girl. What the bleep!

    • paola f. 3 years ago

      Paul Jenkins it’s like asmr, nothing wrong with saying that. it’s not like she looks at her comments all the time anyway

    • Paul Jenkins 3 years ago

      @paola f. all of these compliments that deal with Nancy’s personal attributes, rather than her analytical skills involving mathematics, such as the sound of her voice, her beauty, her sexual energy, etc., merely serve to further spoil her and build her super-sized ego, and provide a tingling feel-good friendship-like connection to the giver. But it’s not real. She is not actually your friend. Complimenting her technical skills and/or her teaching skills, on the other hand, is perfectly acceptable.

      There are so many guys on this thread opening their hearts to Nancy with their warm and sensual comments, wishing they could touch her face and hands and gaze into her eyes in the hopes that fortune would smile upon them and offer a chance for love with her. If only they could have a few moments with Nancy to win her heart and make her fall in love with them. Wouldn’t it be beautiful. Spring is in the air, the Birds are chirping, the Bees are buzzing, and the scent of flowers is everywhere. LOL!

      Sadly, Boys and Men live in a world that has been cleansed of almost all knowledge regarding the proper way to treat and interact with women. Fathers don’t know how to teach their sons to properly engage women in a way that promotes positive relationships and respect for each other. Mothers teach their sons how to behave the way women think men should act, but they don’t have a clue. This leaves society in a gross state of confusion. Hence, I present to you the broken society of the 21st century.

      To complete this conversation and come full circle, it is this total lack of understanding of male/female etiquette that leads men down the wrong path and causes them to fill this thread with blind sensual-based compliments for a woman they have never met, never seen, and never had a conversation with. And this silly behavior is merely a symptom of a much larger problem that is destroying the happiness of men everywhere, which has a residual affect on women as well. This problem has led many men to join MGTOW, which is a solution that actually creates a bigger problem. Men and woman might as well be passengers on the Titanic.

      Most of the time, you’ll get a random angle that you don’t know what its sin/cos/tan are equal to. Unless you’re asked to write a simplified answer (like BC = 8×tan(34) in this video), you’ll most likely need a calculator.

  • I be a DOCTOR 3 years ago

    For people who think they’ll never use math in real life after school: have you ever seen a video of some toothless idiot who cuts down a tree and drops it directly on their own or a neighbor’s house or car? Yeah…a simple plumb bob, carpenter’s square (or protractor) and a working knowledge of trigonometry would’ve stopped that from happening.

    • Dannn Merkle 3 years ago

      Carpenters use this stuff all the time. It’s pretty useful to know how long the boards need to be for a given roof pitch. Electrical engineers too, reactive power calculations and such. If there is one part of highschool math I wish I hammered into my head better it’s this.

    • I be a DOCTOR 3 years ago

      @Dannn Merkle Yes I know. I AM a carpenter and DO use it all the time. That doesn’t negate the fact that there are students who say “I’ll never need to know this.”

    • Dannn Merkle 3 years ago

      @I be a DOCTOR I agree. I was trying to reinforce your point is all.

  • Mark Keating 3 years ago

    Dear Ms. Nancy, thanks for trying to help with this. Is there a rule that says when deciding what [adj] value to use for calculations, to do not use the value of the adjacent side that you’ve just solved for in an earlier step? In the first step of this example, you said to use [adj] since that’s a known value, and solved for [a]. I got confused because we just solved for [a], so I didn’t see any reason why I shouldn’t use that value for [adj] in the next step when we wanted to solve for [c]. In the solving for [a], we used the side (8), which was to the left as seen by the perspective of [A]. As we went to solve for [c], I thought – “OK, well since I know the value of [a] I’ll just use that value. As you probably know, it didn’t work. So – is there a rule that says to not use the value of the side to the left of a right triangle when making these calculations? – Thanks = Mark

  • Gary Lewis 2 years ago

    The thing i would add here is if the angle could have been stated in radian as in 1 rad = 57degs so if you see rads in the problem set your calculators to radians. The majority of diagrams the angle will be in degrees.
    Some programing languages like Lisp used in CAD programs like AutoCAD it takes radians as input.
    So like Cos(a)
    “a” should be in radians.
    For convertion
    a= D×PI/180.
    D is degrees
    PI=3.1415926535

    I used this form in a different way when I was laying out for a slab to pour concrete in. Also to make sure the slab was perfect I would measure from corner to corner. Also to make sure I had a sq corner in the first place I would lay out that corner first and then measure one side 8 foot and the remaining side 6 foot I would then square both measurement and add them together and then ask for the Sq root of that number.
    So 8 sqed 64 and 6 sqed 36 added together is 100 and what number squared gives you 100 is 10 sqed. Now you have a sq corner. Then from that corner you measure out the two remaining lengths and join them together at the other corner then measure the two 10 or what ever that length was and they would be the same and you have a square slab ready to build your house or what ever… Yes was a Contractor for over 60 years who has built lots of homes and commercial buildings of all sizes and shapes and when I say level a plumb bob will tell you your building is straight up and down with no leaning of any kind..

    Easier for me to label the sides as Opposite-hypotenuse-. And adjacent. Because that’s what they are…. That big B lil B and etc is sort of confusing….. The angle always points to the opposite.. the hypotenuse is always the longest side… So that simplifies it… Then u write SOH-CAH-TOA….. then cross out. THE S THE C AND THE T.. then look at what u know! if u see he angle and know it or also have one one of the other side’s that u also know .. like adjacent.. then u grab Ur scientific calculator.. use the shift key (inverse function). because Ur seeking an angle… (That’s when u use shift) then lets say Ur using Tangent of the angle.. so u would press shit.thej Tangent.. then parentheses do your division of the two known sides… Ensuring that u divide opposite over the adjacent or whatever one is in Ur. SOH CAH TOA elimination.. then hit equals key.. the the D.M.S. Key. (degrees minutes and seconds). that’s Ur answer.. also round up or down the seconds portion at the end…(5 or more u round up.. less than five drop it)

    Side c = Side b ÷ Cos of angle A
    Side a = Side c × Sine of angle B
    Side b = Side c x Cos of angle A
    Angle B = 180 – 90 – Angle A
    Angle A = a side ÷ by b side = 2nd function Tangent

  • mehdi darany 2 years ago

    Hello dear Nancy. I am a math teacher in Iran. I am proficient in many software for virtual learning and I can use them to teach my students, but I don’t know how you make these educational videos ?! Do you write on special glass and then teach with a special type of recording and filming? Are you fluent in writing the opposite? If possible, help me make this kind of filming. thank you. daranymehdi@gmail.com

    • Dyson 2 years ago

      Hello, I am not Nancy, but she is using a clear whiteboard to record the videos, and then mirrors her footage so that it looks the right way to us.

  • mehdi darany 2 years ago
