To find the measure of angle \( R \) in triangle \( JRW \), we can use the fact that the sum of the interior angles of a triangle is always 180°.
Given:
- \( m∠J = 47° \)
- \( m∠W = 15° \)
We can calculate \( m∠R \) as follows:
\[ m∠R = 180° - m∠J - m∠W \] \[ m∠R = 180° - 47° - 15° \] \[ m∠R = 180° - 62° \] \[ m∠R = 118° \]
So, the measure of angle \( R \) is \( 118° \).
The correct response is:
m∠R=118°
