Question

Can you please help me out with a question

Answer 1

From the arc-angle relationships, we know that

`20=(3x-11)/(2)`

By moving the denominator to the left hand side, we get

`\begin{gathered} 2*20=3x-11 \\ 40=3x-11 \end{gathered}`

by moving -11 to the left hand side, we have

`\begin{gathered} 40+11=3x \\ 51=3x \end{gathered}`

Then, x is given by

`\begin{gathered} x=(51)/(3) \\ x=17 \end{gathered}`

then, the answer is option J.
