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=118°
m angle upper R equals 118 degrees

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

m∠R=28°

Answer 1

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

You have:

• \( m∠J = 47° \)
• \( m∠W = 15° \)

Now, you 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°
