Trigonometry Pt. 4 - Double Triangle Trig

This video will take the basics we've learned about sin, cos, and tan, and apply them to a slightly more complicated picture. The pictures in these problems contain multiple triangles. The reason I call them "Double Triangle" problems is because they all boil down to working with a pair of triangles in order to solve the problem.

You answered the question I been trying to find all day. You can’t use that triangle because it’s not a right triangle. Makes sense now

Hello! I noticed you stored some numbers in your calculator as A and B would you mind sharing how to do that on a calculator? I have a Casio fx-300ES PLUS

Do you think you could make an email or some sort of platform for people to send specific questions and possibly send you a picture of the problem they are solving? Thanks your videos are so helpful.

Can you do the same topic with isosceles triangle and bottom length?

what if we don't know one of the angle, how do we calculate it
