Question

I tried doing the method my teacher taught me but i keep getting it wrong

Answer 1

x = 12

Step-by-step explanation

By the intersecting chords theorem, the product of each segment of one chord equals to the product of each segment of the other chord:

`15\cdot8=10x`

Solving for x:

`\begin{gathered} 120=10x \\ x=(120)/(10) \\ x=12 \end{gathered}`
