Question

Can someone please help explain how to do this?

What is the measure of B? C is 34 degrees.

Answer 1

m<B= 56

Explanation:

A triangle has 180 degrees. This is right triangle meaning there is one angle that is 90 degrees. That's angle A since it's indicated by the little box. So 90+34= 124. You then subtract that from 180 to get 56.
