Question

which angle is complementary to ∠5?
∠2
∠6
∠3
∠1

Explanation:

Step1: Recall complementary - angle definition

Two angles are complementary if their sum is 90 degrees. In the given intersection of lines, we need to find an angle that forms a right - angle with ∠5.

Step2: Analyze vertical and adjacent angles

Vertical angles are equal and adjacent angles on a straight - line sum to 180 degrees. In this case, we can see that ∠3 and ∠5 are adjacent angles that form a right - angle (assuming the intersection is such that relevant angles are complementary).

Answer:

∠3
