Answer:

C) 16, 6

Step-by-step explanation:

  1. Set AB and DC equal to eachother. 4x = x + 12.
  2. Subtract x from both sides. 3x = 12
  3. Divide by 3 to get x alone. x = 4
  4. Plug this x value in the equation for AB. 4•(4) = 16
  5. We know the AD equals 6, so that will be one of the values and we now know that AB equals 16.
