Question

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=28°
m angle upper R equals 28 degrees

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

m∠R=62°

Answer 1

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 \( 180^\circ \).

Given:

• \( m\angle J = 47^\circ \)
• \( m\angle W = 15^\circ \)

We can find \( m\angle R \) using the following formula:

\[ m\angle R = 180^\circ - m\angle J - m\angle W \]

Substituting in the known values:

\[ m\angle R = 180^\circ - 47^\circ - 15^\circ \] \[ m\angle R = 180^\circ - 62^\circ \] \[ m\angle R = 118^\circ \]

So, the measure of angle \( R \) is \( 118^\circ \).

Correct response:

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