Question

which angle is complementary to ∠6?

Explanation:

Step1: Recall the definition of complementary angles

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

Step2: Analyze the relationship between \(\angle6\) and \(\angle4\)

From the figure, we can see that \(\angle6+\angle4 = 90^{\circ}\) (as they form a right - angle).

Answer:

\(\angle4\)
