To obtain the value of x, the following steps are necessary:

Step 1: Since both triangles CDE and FGE are similar, the following ratio is valid:


(EF)/(CE)=(EG)/(DE)

Step 2: Substitute the value of the lengths of the sides into the ratio as follows:


\begin{gathered} EF=x \\ CE=27 \\ DE=25 \\ EG=40 \\ \text{Thus:} \\ (EF)/(CE)=(EG)/(DE) \\ \Rightarrow(x)/(27)=(40)/(25) \end{gathered}

Step 3: Solve the resulting equation for x, as follows:


\begin{gathered} (x)/(27)=(40)/(25) \\ \Rightarrow x=(40)/(25)*27=(1080)/(25)=43.2 \\ \Rightarrow x=43.2 \end{gathered}

Therefore, the value of x is 43.2 (Option B)
