Question

WXYZ is a parallelogram.Find the of Z

Answer 1

65°

Step-by-step explanation:

Angles in any quadrilateral add up to 360

So we can make a equation:

`360 = 2(18b-11)+2(9b+2)`

`360=36b-22+18b+4`

`360=54b-18`

`378 = 54b`

`b = (378)/(54)`

b= 7

So now you substitute b with 7 to give you:

`9(7)+2`

`63+2`

65°
