Answer:
Hi, there are multiple questions, but to solve all of them you have to use the equation on the top of the page. That is the Pythagorean Theorem.
Basically, you take the angles already given, those will be your A's and B's, and you square them. Once you do that, you add them and apply the square root to find the measure of the hypotenuse. The hypotenuse will be the C's in the equation.
I have a picture of one of your exercises, that's what you have to do for all the exercises on the picture since you have the angles.
