Question

Find a complement of an angle with measure 72 degrees.

Answer 1

"Complementary angles add up to 90 degrees, meaning if you put them right next to each other, you would get a right angle. If you already have one angle, and want to find its complement, simply subtract the measure of that angle from 90 degrees. Since you have a 73 degree angle, the complement would be 17 degrees, since 73 + 17 = 90."
Does that help?
