Question

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

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

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

m∠R=28°
m angle upper R equals 28 degrees

m∠R=118°

Answer 1

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

Given:
- \( m∠J = 47° \)
- \( m∠W = 15° \)

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 \( 118° \).

The correct response is:

m∠R=118°
