An angle and its complement have to add to 90 degrees.
77 and 13 add to 90.
13 is the complement of 77.
You will also be doing supplement. They add to 180.

An angle and its complement sum to ninety degrees. 90-52=38
30 degrees
145 degress

The complement of an acute angle A is the angle 90° - A. The complement of 13° is 77°.
13
The complement is 60 degrees.
13o
An angle and its complement add to 90 degrees. Hence an angle of 41 degrees has 49 degrees as its complement.
The complement of an angle C is (90 - C) So the complement of an angle of 17.7° is (90 - 17.7) = 72.3°
complement is 90 degrees minus angle supplement is 180 degrees minus angle 90-77 = 13 = complement 180-77 = 103 = supplement
15°
The complement is how much you have left after you subtract the first angle from 90 degrees.
