The sum of the angles in a triangle is always 180°. Therefore, we can find the measure of angle R by subtracting the measures of angles J and W from 180°:
R = 180° - 47° - 15°
R = 180° - 62°
R = 118°
Therefore, the measure of angle R is 118°.
△JRW has angle J measuring 47° and angle W measuring 15° . What is the measure of angle R ?
