To find the measure of angle \( R \) in triangle \( JRW \), we can use the fact that the sum of the angles in a triangle is always 180 degrees.
We have:
\[ \angle J = 47^\circ \] \[ \angle W = 15^\circ \]
We can find angle \( R \) using the equation:
\[ \angle R = 180^\circ - \angle J - \angle W \]
Substituting the known values:
\[ \angle R = 180^\circ - 47^\circ - 15^\circ \]
Calculating:
\[ \angle R = 180^\circ - 62^\circ = 118^\circ \]
Therefore, the measure of angle \( R \) is \( 118^\circ \).
