Question

△JRW
has angle J
measuring 47°
and angle W
measuring 15°
. What is the measure of angle R
?(1 point)
Responses

m∠R=118°
m angle upper R equals 118 degrees

m∠R=62°
m angle upper R equals 62 degrees

m∠R=47°
m angle upper R equals 47 degrees

m∠R=28°

Answer 1

In triangle \( \Delta JRW \), the sum of all the angles is \( 180° \). Given that \( m∠J = 47° \) and \( m∠W = 15° \), we can find \( m∠R \) as follows:

\[
m∠R = 180° - m∠J - m∠W
\]

Substituting the known values:

\[
m∠R = 180° - 47° - 15°
\]
\[
m∠R = 180° - 62°
\]
\[
m∠R = 118°
\]

Thus, the measure of angle \( R \) is \( m∠R = 118° \).

The correct response is:

**m∠R=118°**
