Angles r and s are supplementary angles. What is the measure of ∠r if the measure of ∠s = 37°?(1 point) Responses 53° 53° 37° 37° 143° 143° 217°

Answer 1

Supplementary angles are two angles whose measures add up to 180 degrees. Given that the measure of angle \( s = 37^\circ \), we can find the measure of angle \( r \) using the following equation:

\[ r + s = 180^\circ \]

Substituting the value of \( s \):

\[ r + 37^\circ = 180^\circ \]

To find \( r \), subtract \( 37^\circ \) from \( 180^\circ \):

\[ r = 180^\circ - 37^\circ = 143^\circ \]

So, the measure of angle \( r \) is \( 143^\circ \).

The correct response is 143°.
