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°
