Question 422100: How to find one leg (a) and the hypotenuse (c) of a right triangle when one leg (b) is given (9 cm) and the angle closest to it, (angle B I can guess (45 degrees). Answer by shree840(260) (Show Source):
You can put this solution on YOUR website! You need to know the angle. You can not guess or another side need to be given.
use trig
tanA=opposite/adjacent
sinA=opposite/hypotenuse
cosA=adjacent/hypotenuse
