Question

Which angle is supplemental to angle 6?

Select one:

a.
Angle 8


b.
Angle 2


c.
Angle 7


d.
Angle 3

Answer 1

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.
