m angle A = 72 degree. Find the supplement of angle A. Do what?

The "supplement" of an angle in degrees is 180 - the angle

180 - 72 = ?

To find the supplement of angle A, you need to know that the supplement of an angle is defined as 180 degrees minus the angle itself.

In this case, the given angle is 72 degrees. So, to find the supplement, you subtract 72 degrees from 180 degrees.

Supplement of angle A = 180 degrees - 72 degrees = 108 degrees.

Therefore, the supplement of angle A is 108 degrees.
