Final answer:
The complement of an angle is found by subtracting the angle from 90 degrees.
Step-by-step explanation:
The complement of an angle is found by subtracting the angle from 90 degrees. Let's find the complement for each angle:
a. 28°: The complement of 28° is 90° - 28° = 62°.
b. 53°: The complement of 53° is 90° - 53° = 37°.
