?(1 point)
Responses

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

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

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

m∠R=28°

Answer 1

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

We know:
- m∠J = 47°
- m∠W = 15°

Now, we can calculate m∠R as follows:

\[
m∠R = 180° - (m∠J + m∠W)
\]
\[
m∠R = 180° - (47° + 15°)
\]
\[
m∠R = 180° - 62°
\]
\[
m∠R = 118°
\]

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

The correct response is:
m∠R=118°
