The answer is that the measure of angle A is

To determine the measures of angles A and B, we set up an equation based on the fact that supplementary angles add up to 180 degrees. Angle A is represented by

Substituting this value of x back into the expressions for A and B, we find that the measure of angle A is
degrees, and the measure of angle B is

Therefore, the solution indicates that when \(x\) is
angle A measures \
degrees, and angle B measures
degrees. This satisfies the condition that the two angles are supplementary, with their sum equaling 180 degrees.
The probable question maybe:
If the measure of angle A is given by
and the measure of angle B is
and the angles are supplementary, what is the measure of each angle?
