Question

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

Explanation:

Step1: Recall supplementary - angle definition

Two angles are supplementary if their sum is 180 degrees. Adjacent angles formed by two intersecting lines are supplementary.

Step2: Identify adjacent angle to ∠5

In the given figure, ∠5 and ∠6 are adjacent angles formed by the intersection of two lines. So, ∠5+∠6 = 180 degrees.

Answer:

∠6
