Question

How do you find the missing angles when the sides of a right triangle are given?

Answer 1

In Triangle `ABC` with the right angle at `C`, let `a`, `b`, and `c` be the opposite, the adjacent, and the hypotenuse of `angle A`. Then, we have

`sin A=a/c Rightarrow "m"angle A=sin^{-1}(a/c)`

`sin B=b/c Rightarrow "m"angle B=sin^{-1}(b/c)`
