work it out

Explanation:

Step1: Recall complementary angles definition

Complementary angles add up to 90°.

Step2: Analyze the given angle - pair options

In the figure, if there is a right - angle marked, we need to find pairs that make up 90°. Looking at the options:

• For ∠2 and ∠5: Since there is a right - angle formed where ∠2 and ∠5 are adjacent, ∠2+∠5 = 90°.
• For ∠6 and ∠1: There is no indication that their sum is 90°.
• For ∠1 and ∠4: There is no indication that their sum is 90°.
• For ∠2 and ∠1: There is no indication that their sum is 90°.

Answer:

∠2 and ∠5
