Two angles are complementary if the sum of their measures is 90^(∘). | Two angles are supplementary if the sum of their measures is 180^(∘). |
We are told that the measures of two angles are 62^(∘) and 108^(∘). To determine whether they are complementary, supplementary, or neither, we will calculate the sum of their measures. 62^(∘) + 108^(∘) = 180^(∘) Since the sum is 180^(∘), the angles are supplementary.
