Question

Given parallelogram WXYZ, WV = 5x - 5, and WY = 20, find the value of x. (Please note, canvas is broken so I had to rewrite it.)

Answer 1

we have

WV = 5x -- 5

WY = 20

and WV = 1/2 WY

So

`\begin{gathered} WV=(1)/(2)WY \\ 5x-5=(1)/(2)(20) \\ 5x-5=10 \\ 5x-5+5=10+5 \\ 5x=15 \\ (5x)/(5)=(15)/(5) \\ x=3 \end{gathered}`

answer: x = 3
