Since angle B is supplementary to both angles C and D, either of these angle measures may be used to determine the measure of Angle B. Using the measure of either angle C or angle D, we find the measure of angle B to be 180 − (180 − x) = 180 − 180 + x = x. Therefore, both angle A and angle B have measures equal to x and are equal in measure.
