You would set AC and AB equal to each other to find out what x is. 

x+9=2x-8
x+17=2x
17=1x
17=x

Since CB is just x, CB equals 17.

Aneli [31]

Answer:

  • Option A

Step-by-step explanation:

We can solve this with the help of Pythagoras theorem.

  • => (√50)² = x² + x²
  • => √50 x √50 = x² + x²
  • => 50 = 2x²
  • => 25 = x²
