Question

Find the value of x.

Answer 1

Answer 4

x will always be 4

Answer 2

x = 6

Explanation:

You want the missing length of a chord with one length 10. It crosses a chord with lengths 5 and 12.

Crossed chords

The product of the segment lengths for two crossed chords is the same for each:

x · 10 = 5 · 12

x = 60/10 = 6 . . . . . . divide by the coefficient of x

The value of x is 6.
