Equation practice with angles

Problem

The angle measurements in the diagram are represented by the following expressions.
space, start color blueD, angle, A, end color blueD, equals, start color blueD, 5, x, plus, 20, degree, end color blueD space, start color green, angle, B, end color green, equals, start color green, 9, x, minus, 92, degree, end color green
Solve for x and then find the measure of start color blueD, angle, A, end color blueD:
start color blueD, angle, A, end color blueD, equals
