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

Essay

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 $180 ^ { \circ }$ .) $\angle A =$ __________ $0$ $\angle B =$ __________ $∘$ $\angle C =$ __________ $∘$
