Question

Which pair of angles are supplementary?

a. ∠ZVSW and ∠ZWSR
b. ∠ZUSV and ∠ZVSW
c. ∠ZTSV and ∠ZVSW
d. ∠ZTSR and ∠ZUSW

Answer 1

The pair of angles that are supplementary is ∠ZTSR and ∠ZUSW.

Step-by-step explanation:

The pair of angles that are supplementary is option d. ∠ZTSR and ∠ZUSW.

To be supplementary, the sum of the angles must be 180°.

We can find the sum of these two angles:

Sum of the angles: 20° + 20° = 40°

Since the sum is not 180°, these angles are not supplementary.
