GPT-4o mini · Answer

To find the measure of angle R in triangle JRW, we can use the fact that the sum of the angles in any triangle is always 180 degrees.

We know:

Now, 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 \( m∠R = 118° \).

The correct response is: m∠R=118°
