△JRW has angle J measuring 47° and angle W measuring 15°. What is the measure of angle R?(1 point)
1.m∠R=118°
2.m∠R=28°
3.m∠R=62°
4.m∠R=47°
To find the measure of angle R, we know that the sum of the angles in a triangle is 180 degrees.
Therefore, angle R = 180 - angle J - angle W
= 180 - 47 - 15
= 118°
So, the measure of angle R is 118°.
The correct answer is (1) m∠R = 118°.
To find the measure of angle R, we need to subtract the measures of angles J and W from 180° (since the sum of the angles in a triangle is 180°).
180° - 47° - 15° = 118°
So the measure of angle R is 118°.
Therefore, the correct answer is 1. m∠R=118°.
