Question

the measure of "x" in the figure is (AB and CD are parallel)

Answer 1

Answer:

Draw a line which is parallel to AB and CD, and divides the angle x in two parts y and z. If a transversal line intersect two parallel lines, then interior angles on same sides are supplementary angles. It means the sum of interior angles on same sides is 180°. Angle with measures y and 48 are supplementary angles.
