Question

angles 1 and 2 are supplementary. which equation represents the relationship between their measures? o m∠1 + m∠2 = 90° o m∠1 + m∠2 = 100° o m∠1 + m∠2 = 180° o m∠1 + m∠2 = 200°

Explanation:

Step1: Recall supplementary - angle definition

Supplementary angles add up to 180°.

Answer:

m∠1 + m∠2 = 180°
