To find the measure of the angle you need your calculator. We are given two sides that go with the angle we need to find. These two sides are the opposite side, and the adjacent side.

Because of the sides given we will be using tangent. Opposite/adjacent which is 36/32
When we insert that into the calculator we get 1.125, which isn’t the answer. Click second and then tan on your calculator and insert 1.125. The answer is the angle measure we need, which is 48.37 but 48.4 if we round it.
