Question

1. if angles are called complementary, what is the sum of their measures? 180 degrees 45 degrees 360 degrees 90 degrees

Explanation:

Complementary angles are defined as two angles whose sum is \(90^{\circ}\). For example, if one angle is \(30^{\circ}\), its complementary angle is \(90 - 30=60^{\circ}\). Angles that sum to \(180^{\circ}\) are called supplementary, \(360^{\circ}\) is a full - circle measure, and \(45^{\circ}\) is just a single angle measure that doesn't define the complementary relationship.

Answer:

90 degrees
