Question

What does X=
10
8
9
……..

Answer 1

8 because 4+4=8 and 5+5=10

Answer 2

x = 8

Explanation:

Given 2 intersecting chords in a circle.

Then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

5x = 10 × 4 = 40 ( divide both sides by 5 )

x = 8
