Question

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


1.m∠R=118°

2.m∠R=28°

3.m∠R=62°

4.m∠R=47°

Answer 1

To find the measure of angle R, we know that the sum of the angles in a triangle is 180 degrees.

Therefore, angle R = 180 - angle J - angle W
= 180 - 47 - 15
= 118°

So, the measure of angle R is 118°.

The correct answer is (1) m∠R = 118°.
