△JRW has angle J measuring 47° and angle W measuring 15° . What is the measure of angle R ?(1 point) Responses m∠R=28° m angle upper R equals 28 degrees m∠R=118° m angle upper R equals 118 degrees m∠R=47° m angle upper R equals 47 degrees m∠R=62°

1 answer

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°.
