Question

which angle is complementary to ∠2?

Explanation:

Step1: Recall the definition of complementary angles

Complementary angles are two angles whose sum is \(90^{\circ}\).

Step2: Analyze the given angles

From the diagram, we can see that \(\angle2+\angle3 = 90^{\circ}\) (as they form a right - angle together).

Answer:

\(\angle3\)
