A= 51 (vertically opposite) B= 129 (angles on a straight line and supplementary angles) D= 129 (vertically opposite) W= 129 (corresponding angles) X = 51 (co-interior angles, angles on a straight line, supplementary angles and corresponding angles) Y = 129 (vertically opposite) Z = 51 (supplementary angles, angles on a straight line)
PART B Z and y are supplementary angles because they are on a straight line meaning they add up to 180 degrees.
