Since triangles ABC and BCD are similar, we can establish a proportion between the lengths of corresponding sides:
We can infer from our picture that
. Also we can find the length of AC by adding AD and CD:
Lets replace the values in our proportion:
Solving for
:
We can conclude that the correct answer is: D
