Answer:
A
Step-by-step explanation:
I don't know if this is how i'm supposed to explain it, but AC is twice the size of DF, and DF is twice the size of CF
Pretend that DF is 2 inches, then AC is 4 inches and CF is 1 inch, so you get this:
![{DC}^{2} = CF \times AC](https://tex.z-dn.net/?f=%20%7BDC%7D%5E%7B2%7D%20%20%3D%20CF%20%5Ctimes%20AC)
9/21 + 14/21 = 23/21 or 1 and 2/21
