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

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

m∠R=28°
m angle upper R equals 28 degrees

m∠R=62°

Answer 1

In triangle △JRW, the sum of the angles is always 180°. You can find the measure of angle R by using the formula:

m∠R = 180° - m∠J - m∠W

Given:
- m∠J = 47°
- m∠W = 15°

Now, substitute the values into the formula:

m∠R = 180° - 47° - 15°
m∠R = 180° - 62°
m∠R = 118°

Therefore, the measure of angle R is 118°.

The correct response is:
m∠R = 118°
