This problem involves solving for $x$ in two similar triangles. We can apply the concept of similar triangles to set up a proportion between corresponding sides.

The triangles $\triangle JML$ and $\triangle JNK$ are similar, so we can use the corresponding side lengths to form a proportion.

From the diagram:

• $JL$ corresponds to $JK$.
• $JM$ corresponds to $JN$.
• $ML$ corresponds to $NK$.

The sides provided are:

• $JM = 6.8$, $JN = 3.4$
• $ML = x$, $NK = 5.6$

We can set up the proportion: $\frac{JM}{JN} = \frac{ML}{NK}$ Substitute the known values: $\frac{6.8}{3.4} = \frac{x}{5.6}$ Simplify the left side: $2 = \frac{x}{5.6}$ Now solve for $x$: $x = 2 \times 5.6 = 11.2$

The value of $x$ should be $11.2$. It seems the answer entered, $4.1$, is incorrect based on the given information.
