Question

1. what is the sum of the measures of a pair of complementary angles? 90° 45° 180° 360°

Explanation:

Complementary angles are defined as two angles whose sum is \(90^{\circ}\). For example, if one angle is \(30^{\circ}\), the other angle that is complementary to it is \(90^{\circ}- 30^{\circ}=60^{\circ}\), and \(30^{\circ}+60^{\circ}=90^{\circ}\).

Answer:

\(90^{\circ}\)
