Answer:

Step-by-step explanation:

The formula for finding the relationship between a secant and a tangent is

tangent length ^2 = external segment secant/full length of secant

In this case

60^2 = 48*(x + 48) Expand

3600 = 48*(x + 48) Remove the brackets/

3600 = 48x + 48^2 Expand

3600 = 48x + 2304 Subtract 2304 from both sides

3600 - 2304 = 48x

1296 = 48x Divide both sides by 48

1296 / 48 = x

x = 27
