What is the complement and supplement of an angle?

Answer by  Monica21 (11)

Suppose the angle is 'x' degrees. Then the complement of angle 'x' will be equal to the difference between 90 degrees and 'x' degrees. Therefore, complement of angle 'x' = 90 - x. The supplement of angle 'x' will be equal to the difference between 180 degrees and 'x' degrees. Therefore, supplement of angle 'x' = 180 - x.

The complement of an angle A that is less than 90 degrees is 90-A. The supplement of an angle B that is less than 180 degrees is 180 - B.
