Question

Find the value of x. If necessary, round your answer to the nearest tenth. The

figure is not drawn to scale.

Answer 1

12

Explanation:

If two chords intersect in a circle, then (product of segments of Chord 1) = (product of segments of Chord 2)

=> 8 × 15 = 10 × x

=> x = 8 × 15 ÷ 10

=> x = 12
