Question

What is the m∡U in the figure shown?

Answer 1

∠ U = 70°

Explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ RVU is an exterior angle of the triangle , then

∠ U + 50° = 120° ( subtract 50° from both sides )

∠ U = 70°

Answer 2

m<U=70

Explanation:

we know that the measure of the out side angle is equal to the measure of the 2 inside angles, so 120-50=70
