Question

In triangle ABC, shown below, find the measure of angle B. Round to the nearer degree. Use any appropriate trigonometric ratio.

Answer 1

Well you can tell that it's a right triangle because it is a pythagorean triple so one angle is 90 degrees! then you can use sin law if you need more help just ask

Answer 2

I'm afraid that I don't know how to solve for it, though. If you can, could you walk me through it, please? Thank you kindly for your help. (^_^)

Answer 3

Ofcourse I can help!

Answer 4

So the angle and the opposite sides correspond when using Sin Law

Answer 5

So 90 degrees would correspond to 13

Answer 6

B would correspond to 12 and A to 5. Do you get that so far?

Answer 7

Yes, I understand that. (^_^)

Answer 8

Okay okay, So sin law works like this
