Question

Solve for X. Assume that lines which appear tangent are tangent​

Answer 1

x = 16 and x = 15

Explanation:

Given 2 chords intersecting then the product of the parts of one chord is equal to the product of the parts of the other chord.

(3)

7x = 14 × 8 = 112 ( divide both sides by 7 )

x = 16

(1)

8x = 12 × 10 = 120 ( divide both sides by 8 )

x = 15
