△JRW has angle J measuring 47° and angle W measuring 15° . What is the measure of angle R ?

1 answer

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 degrees.

We have:

\[ \angle J = 47^\circ \] \[ \angle W = 15^\circ \]

We can find angle \( R \) using the equation:

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

Substituting the known values:

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

Calculating:

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

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