👉 Learn how to find a missing side length of a right triangle. A right triangle is a triangle that has 90 degrees as one of its angles. The trigonometric identities of right triangles give us the relationship between the angles of a right triangle and the side lengths of the right triangle. These trigonometric identities, commonly called SOHCAHTOA, are: sin x = opposite / hypothenuse; cos x = adjacent / hypothenuse and tan x = opposite / adjacent. These identities enable us to find a missing side length of a right triangle given one of the side lengths and one of the other angles of the right triangle.

@jillybrownie2390 Год назад

I have a question, and if anyone can help me out, please do! So we know that the right angle is 90 degrees. We know that the given angle is 63 degrees. Why can't we add those two numbers and subtract them from 180 in order to obtain the last angle? Why doesn't this work here?

@studywithme5998 2 года назад

here is a small tip to make this easier and faster, so instead of doing all the algebra at 3:40 you can just cross multiply sin36=12/x so it becomes x=12/sin36 straight away that's how my teacher taught us and I kinda find it a bit easier than having to do all that algebra. thnx tho this vid was actually very helpful cause I needed to shake my memory before the test lol

@IDcLuc 6 месяцев назад

This is such a good explanation, but the way I learned it wasn't to multiply by x then divide by sin63° but just to cross multiply: sin63 °= 12/x sin63°/1 = 12/x 12*1/sin63° 12/sin63°

@jahongirtolqinboyev4021 3 года назад

A teacher who uses a method that is accurate and easy for students to understand. It is very useful to use such methods because in this video it is not easy to explain everything, sometimes we can not understand everything. But I admire this teacher for teaching. He was able to explain everything to us. I was given this topic today. But I couldn’t understand a bit, especially finding the sides. And now I understand everything 100 percent. Thanks for such a video lesson!!!

@stevenhodgkiss442 3 года назад

Thanks Brian! You helped this old man figure out the length of 3 legs of a wooden stool project I am working on based upon the desired height. I am sure your students are benefiting greatly from your teaching skills. Calling on the students by name is very effective too. I am sure you have noticed that it helps keep them engaged and feel important enough to participate. We need more teachers like you to teach the next generation of programmers, engineers, builders, entrepreneurs, architects, makers, biochemists, energy scientists, space workers and all other STEM related occupations. Even old and soon to be retired woodworkers like me. This was a great refresher course too.

I just got a new TI-84 calculator. Monstrous computing power. But it came up with a BIG difference in answer to the problem on the board. Finally one sentence you said at the 3:57 mark got through to my brain - "Make sure our calculators are in degrees mode". Mine wasn't. Such an expensive calculator should know what mode I want to be in. So, I had to MANUALLY change over from Radians to Degrees. Your answer is correct. Thought you'd like to know.
