Question

Find the value of x.

Answer 1

x=10

Explanation:

Secant-Secant Formula:

(whole secant) x (external part) =(whole secant) x (external part)

(x-8+4) * 4 = ( x-5+3) * 3

Combine like terms

( x-4) *4 = ( x-2 ) * 3

Distribute

4x-16 = 3x-6

Subtract 3x from each side

4x-3x -16 = 3x-3x-6

x-16 = -6

Add 16 to each side

x-16+15 = -6+16

x=10
