Tel Chords intersecting Theorem 3, Solve for X?

Answer 1

x = 10

Explanation:

You want to find the value of x, where a chord of segment lengths 9 and x crosses a chord of segment lengths 6 and 15.

Intersecting chords

The product of the segment lengths is the same for intersecting chords:

9x = 6·15

x = 90/9 . . . . divide by 9

x = 10
