In the Triangle $\angle B$ Is $20 ^ { \circ }$ More Than

Multiple Choice

In the triangle, $\angle B$ is $20 ^ { \circ }$ more than $\angle A$ , and $\angle C$ is $20 ^ { \circ }$ less than twice $\angle A$ . Find each angle in the triangle. ( Hint: The sum of the angles in a triangle is $180 ^ { \circ }$ .)

A) $\angle A = 60 ^ { \circ } , \angle B = 40 ^ { \circ } , \angle C = 80 ^ { \circ }$
B) $\angle A = 55 ^ { \circ } , \angle B = 75 ^ { \circ } , \angle C = 50 ^ { \circ }$
C) $\angle A = 35 ^ { \circ } , \angle B = 55 ^ { \circ } , \angle C = 90 ^ { \circ }$
D) $\angle A = 45 ^ { \circ } , \angle B = 65 ^ { \circ } , \angle C = 70 ^ { \circ }$
E) $\angle A = 70 ^ { \circ } , \angle B = 50 ^ { \circ } , \angle C = 60 ^ { \circ }$
