Question

WXYZ is a parallelogram. After solving, b =So m

Answer 1

It is given that the quadrilateral WXYZ is a parallelogram.

By property of parallelogram the adjacent angles are supplementary so it follows:

`\begin{gathered} \angle W+\angle Z=180 \\ 18b-11+9b+2=180_{} \\ 27b=189 \\ b=7 \end{gathered}`

Since the value of b is 7, the angle Z is given by:

`\angle Z=9b+2=9(7)+2=65^(\circ)`

Hence b=7 and angle Z is 65 degrees.
