Question

in the given figure, if ab parallel DC and angle BDC is equal to 30 degree ,angle BAD is equal to 80 degree find angle and Angle x, y and z

Answer 1

angle x=30°because alternate angles
angle x+y-30°=180°because adjacent angles of parallelogram are supplementary
angle z=80°because opposite sides of parallelogram are always equal

Answer 2

x = 30°
y= 70°
z = 110°
