The definition of complementary is two angles together that form a right angle or 90 degrees. The way to find the complement of an angle is to subtract that angle from 90 degrees. In this case 90 subtracted by 79 equals 11. The complement of a 79 degree angle is an 11 degree angle.
The complement of an angle C is (90 - C) So the complement of an angle of 17.7° is (90 - 17.7) = 72.3°

It is a 34 degree angle
another angle, of 53 degrees
Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.

90 - 40 = 50 degrees.
90 degrees
The complement of any angle, given that the angle is less than 90 degrees, is 90 minus the angle measure. In other words, it is, "What degree measure, when added to the original angle, creates 90 degrees?"
