Question

for each pair of angle measures, decide if the angles are complementary, supplementary, or neither. complementary supplementary neither 80° and 100° 50° and 50° 25° and 155° 12° and 78°

Explanation:

Step1: Recall the definitions

Complementary angles sum to \(90^{\circ}\), supplementary angles sum to \(180^{\circ}\).

Step2: Check \(12^{\circ}\) and \(78^{\circ}\)

Calculate \(12 + 78=90\).

Answer:

Complementary: \(12^{\circ}\) and \(78^{\circ}\)
