Answer:

x = 9

Explanation:

You have to use the Secant Segment theorem:

AB * AC = AD * AE

This means that the external piece of the secant times the whole secant for one is equal to the external piece of the secant times the whole secant for the other.

Now, setup an equation:

8(x + 8) = 4(30 + 4)

Simplify:

8x + 64 = 120 + 16

8x = 72

x = 9
