△JRW has angle J measuring 47° and angle W measuring 15°. What is the measure of angle R?(1 point)
Responses
m∠R=62°
m angle upper R equals 62 degrees
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
The correct answer is:
m∠R=118°
Angle R is the remaining angle in the triangle, so it can be found by subtracting the measures of angles J and W from 180°.
180° - 47° - 15° = 118°
