Answer:

24

Step-by-step explanation:

Objective: Circle Theorems. Understand that if two tangents of a circle are tangent to the same point, they are equal.

Using that this means that

DB equal CB.

5x + 20 = 10x + 16

20 = 5x + 16

4 = 5x

x =  \frac{4}{5}

Plug in line CB, 5x+20 to find the answer.

5( \frac{4}{5} )  + 20 = 24
