Question

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

Explanation:

Step1: Recall definition of complementary angles

Two angles are complementary if their sum is 90 degrees. In the given figure, we assume there is a right - angle formed where $\angle2$ and $\angle3$ are adjacent angles that make up a right - angle.

Step2: Determine the complementary angle

Since $\angle2+\angle3 = 90^{\circ}$, $\angle3$ is complementary to $\angle2$.

Answer:

$\angle3$
