Question

Examine the diagram of circle A, where DB and CB are tangent to circle A at points D and C. Also, DB = 102 + 16 and CB = 52 + 20.D

Answer 1

Answer: The answer is 24.

Step-by-step explanation: x=4/5, so 5(4/5)+20 = 24.

Answer 2

Given:

DB and CB are the tangent to the circle A.

`\begin{gathered} DB=CB \\ 10x+16=5x+20 \\ 10x-5x=20-16 \\ 5x=4 \\ x=(4)/(5) \end{gathered}`

2nd option is the final answer.
