Question

Find the value of x.

Answer 1

Answer:

x = 3

Step-by-step explanation:

Given 2 intersecting chords, then

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

5x × x = 5 × 9

5x² = 45 ( divide both sides by 5 )

x² = 9 ( take the square root of both sides )

x = $\sqrt{9}$ = 3
