Answer 1

Supplementary angles are two angles whose measures add up to 180°. If the measure of angle \(s\) is \(37°\), then the measure of angle \(r\) can be found by subtracting the measure of angle \(s\) from 180°:

\[
\text{measure of } ∠r = 180° - \text{measure of } ∠s
\]

\[
\text{measure of } ∠r = 180° - 37° = 143°
\]

Therefore, the measure of angle \(r\) is \(143°\).

The correct response is: **143°**.
