Question

A parallelogram is formed by the supports that attach a basketball backboard and rim tothe wall. The angles change as the basketball apparatus is taken out and put away. FindMZADC when mZDAB = 749BDC16°o o7401640106°

Answer 1

In a parallelogram opposite angle are equal

Hence

Sum of angles in a parallelogram = 360 degrees

74 + 74 + x +x + 360

148 +2x =360

360 -148 = 2x

212 = 2x

212/2 =2x/2

x = 106 degrees
