Two parallel lines are intersected by a transversal. One angle measures 125°. Find the measure of the angle x, if angle x is supplementary to the 125° angle. Two parallel lines are intersected by a transversal. One angle measures 62°. Find the measure of the angle x, if angle x is an alternate interior angle to the 62° angle. Two parallel lines are intersected by a transversal. One angle measures 48°. Find the measure of the angle x, if angle x is a corresponding angle to the 48° angle.
