Question

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

Explanation:

Step1: Recall complementary - angle definition

Two angles are complementary if their sum is 90 degrees. In a right - angled intersection of lines, adjacent angles can be complementary.

Step2: Analyze the given angles

From the figure, we can see that ∠2 and ∠5 together form a right - angle (assuming the lines intersect at right angles or there is a right - angle relationship indicated by the context). So, ∠2+∠5 = 90°.

Answer:

∠5
