Solve the triangle. Triangle A B C has a vertex angle labeled C that measures 64 degrees, a base angle labeled B that measures 53 degrees, and a base angle labeled A that does not have a given measurement. The side connecting angle A to angle C is labeled b. The side connecting angle C to angle B is labeled a and measures 10 units. The base leg connecting angle B to angle A is labeled c. 64 degrees a equals 10 53 degrees b c Upper C A
