Question

Which angles are supplementary
to <6? Select all that apply.

Answer 1

∠3

Explanation:

Supplementary angles are angles that add up to 180°. Angle 6 is a right angle, so it's worth 90°. This means that the other angle(s) have to be 90° as well.

As you can see, the other angle with 90° is angle 3, thus, making it the correct answer.
