What is the measure of its supplement and angle?

Answer by  flickr (19)

Supplementary angles are angles that add up to a total of 180 degrees. For example, if you have a 52 degree angle, then its supplement is 128 degrees.

The supplement of an angle is the difference of the angle from 180 degrees. So, if A is your angle, then 180-A degrees is the supplementary angle. An equivalent definition called the complement applies to 90 degrees. Complement of A = 90-A degrees
