measuring 47°
and angle W
measuring 15°
. What is the measure of angle R
?(1 point)
Responses

m∠R=62°
m angle upper R equals 62 degrees

m∠R=118°
m angle upper R equals 118 degrees

m∠R=28°
m angle upper R equals 28 degrees

m∠R=47°

Answer 1

In triangle JRW, the sum of the interior angles is always 180 degrees. Given that angle J measures 47° and angle W measures 15°, we can find angle R by using the following calculation:

\[
m∠R = 180° - (m∠J + m∠W)
\]
\[
m∠R = 180° - (47° + 15°)
\]
\[
m∠R = 180° - 62°
\]
\[
m∠R = 118°
\]

Thus, the measure of angle R is \( m∠R = 118° \).

The correct response is:
m∠R=118°
