Answer:
x=10
Step-by-step 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
