Question

Find the measure of the angle complementary to the given angle. mZy = 15°

Answer 1

Answer: 75 degrees

Step-by-step explanation:

The definition of a "complementary angle" is adding up to 90 degrees, and if one of the angles is 15 degrees, that angle measure and the unknown angle measure must add up to 90 degrees. To find the unknown, we subtract 15 from 90, and we get 75. Therefore, the answer is 75 degrees.
