Since the triangles are similar, the ratios of their corresponding sides are equal. Let's denote the sides of triangle one as \( a = 30.6 \) in and \( b = 25.8 \) in, and the corresponding sides of triangle two as \( c = 13.7 \) in and \( d = x \).

The ratio of the sides can be established as follows:

\[
\frac{a}{c} = \frac{b}{d}
\]

Substituting in the known values:

\[
\frac{30.6}{13.7} = \frac{25.8}{x}
\]

To find \( x \), we can cross-multiply:

\[
30.6 \cdot x = 25.8 \cdot 13.7
\]

Calculating the right side:

\[
25.8 \cdot 13.7 = 352.26
\]

Now we have:

\[
30.6x = 352.26
\]

Next, divide both sides by \( 30.6 \):

\[
x = \frac{352.26}{30.6} \approx 11.5
\]

Thus, rounded to the nearest tenth:

\[
x \approx 11.5 \, \text{in}
\]

Therefore, the value of \( x \) is \( \boxed{11.5} \) inches.
