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

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

m∠R=47°
m angle upper R equals 47 degrees

m∠R=28°

In triangle \( \Delta JRW \), the sum of all the angles is \( 180° \). Given that \( m∠J = 47° \) and \( m∠W = 15° \), we can find \( m∠R \) as follows:

\[ m∠R = 180° - m∠J - m∠W \]

Substituting the known values:

\[ m∠R = 180° - 47° - 15° \] \[ m∠R = 180° - 62° \] \[ m∠R = 118° \]

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

The correct response is:

m∠R=118°
