measuring 47°
and angle W
measuring 15°
. What is the measure of angle R
?(1 point)
Responses

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

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

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

m∠R=28°

Answer 1

In triangle △JRW, the sum of the angles must equal 180°. Given that angle J measures 47° and angle W measures 15°, we can find the measure of angle R using the following steps:

1. Calculate the sum of angles J and W:
\[
47° + 15° = 62°
\]

2. Subtract this sum from 180° to find angle R:
\[
m∠R = 180° - 62° = 118°
\]

Therefore, the measure of angle R is \( m∠R = 118° \).

The correct response is:
- m∠R=118°.
