To find the measure of angle R in triangle JRW, we can use the fact that the sum of the angles in a triangle is always 180 degrees.
We know:
- m∠J = 47°
- m∠W = 15°
We can find m∠R by using the formula:
m∠R = 180° - m∠J - m∠W
Substituting the known values:
m∠R = 180° - 47° - 15° m∠R = 180° - 62° m∠R = 118°
Therefore, the measure of angle R is m∠R = 118°.
