Find the value of x. Then, find the measure of each angle. In triangle A B C, vertex A is at the bottom left, vertex B is at the bottom right, and vertex C is in the middle at the top. The sides can be traced as follows in the counterclockwise direction starting at vertex A: to the right, up and to the left, down and to the left. The angles are labeled as follows: A, 3 x; B, 5 x; C, 4 x.
