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

m∠R=62°
m angle upper R equals 62 degrees

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

m∠R=47°

Answer 1

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°.

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°

Therefore, the measure of angle R is:

m∠R = 118°
