ANSWER


C)\text{ }13

Step-by-step explanation

To find the value of x, we have to apply the intersecting secant theorem which states that if two secants are drawn to a circle from an external point, then:

This implies that:


7*(7+17)=8*(8+x)

Solve for x by simplifying and collecting like terms:


\begin{gathered} 7*24=64+8x \\ \\ 168=64+8x \\ \\ 8x=168-64=104 \\ \\ x=(104)/(8) \\ \\ x=13 \end{gathered}

The correct answer is option C.
