Answer:

∠1 and ∠2

Explanation:

Angle 1 and Angle 2 are the only complementary angles because they form a right angle, which is worth 90°.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer: Choice A only

Angles 1 and 2 add to 90 degrees, ie they join to form a right angle.

Put another way, angles 1,2, and 3 form a straight angle (180 degrees). Angle 3 is 90 degrees, so angles 1 and 2 make up the other 90.
