The value of x is 9.

Given:

The length of the tangent lines are given as, 5x and 7x-18.

The objective is to find the value of x.

The two tangents of a circle drawn from a point outside a circle will always be equal.

Then, the value of x can be solved by,


\begin{gathered} 5x=7x-18 \\ 5x-7x=-18 \\ -2x=-18 \\ x=-(18)/(-2) \\ x=9 \end{gathered}

Hence, the value of x is 9.
