△JRW has angle J measuring 47° and angle W measuring 15° . What is the measure of angle R ?(1 point)
Responses
A) m∠R=62°
B) m∠R=118°
C) m∠R=28°
D) m∠R=47°
Since the sum of the angles in a triangle is 180 degrees, we can find the measure of angle R by subtracting the measures of angles J and W from 180 degrees.
180 - 47 - 15 = 118
Therefore, the measure of angle R is 118 degrees.
Answer: B) m∠R=118°
