Question

which angle is supplementary to ∠4? ∠5 ∠2 ∠6 ∠1

Explanation:

Step1: Recall supplementary - angle definition

Two angles are supplementary if their sum is 180°. Adjacent angles that form a straight - line are supplementary.

Step2: Identify the angle adjacent to ∠4 forming a straight - line

∠4 and ∠2 form a straight - line. So, ∠4+∠2 = 180°.

Answer:

∠2
