type a response

Explanation:

Step1: Apply Intersecting Chords Theorem

When two chords intersect in a circle, the products of the lengths of their segments are equal. So, \( x \times 9 = 18 \times 8 \)

Step2: Solve for \( x \)

First, calculate the right - hand side: \( 18\times8 = 144 \)
Then, we have the equation \( 9x=144 \). Divide both sides by 9: \( x=\frac{144}{9}=16 \)

Answer:

\( 16 \)
