Question

which angle is complementary to ∠2? ∠6 ∠5 ∠3 ∠4

Explanation:

Step1: Recall definition of complementary angles

Complementary angles add up to 90°.

Step2: Analyze the angle - relationship in the figure

Assume the right - angle formed in the figure is composed of ∠2 and another angle. Since the sum of angles around a point where two lines intersect is 360° and a right - angle is 90°. If we consider the angles formed at the intersection, and we know that ∠2 and ∠3 together form a right - angle.

Answer:

∠3
