Answer:
C
Step-by-step explanation:
Triangle CGF and triangle CED are similar. Hence, the ratio of their corresponding sides are equal. Thus we can write:

<em>We can now cross multiply and solve for CD:</em>

Since GF is a midsegment of CDE, CD is double of CF. So we can write:

<em>By using quadratic formula
and with a=3, b= -5.2, and c= -1.6, we find the value of x to be:</em>

<em>Since the expression for CD is
, we plug in
into this expression to find value of CD:</em>

The correct answer is C
