To find the measure of angle R, we can use the fact that the sum of the angles in a triangle is always 180°.

We know that angle J measures 47° and angle W measures 15°. Therefore, the sum of angles J and W is 47° + 15° = 62°.

Since the sum of the angles in a triangle is 180°, we can set up the equation:

Angle J + Angle W + Angle R = 180°

Plugging in the known values, we have:

62° + Angle R = 180°

To solve for Angle R, we need to isolate it. We can do that by subtracting 62° from both sides of the equation:

Angle R = 180° - 62°

Simplifying, we get:

Angle R = 118°

Therefore, the measure of angle R is 118°.
