The image shows two trapezoids, and the problem likely involves using the fact that these trapezoids are similar. In similar figures, corresponding sides are proportional.

The side lengths of the trapezoids are:

- Left trapezoid: \(x+6\), 6, and 12
- Right trapezoid: 9, 21, and 18

Since these trapezoids are similar, we can set up the proportion between corresponding sides. We'll pair the sides of the trapezoids:

1. \( \frac{6}{9} \) (corresponding smaller sides)
2. \( \frac{12}{18} \) (corresponding larger sides)
3. \( \frac{x+6}{21} \) (corresponding sides with \(x+6\))

Now, let's solve for \(x\) using these proportions.

\[
\frac{x+6}{21} = \frac{6}{9}
\]

Simplify \( \frac{6}{9} \):

\[
\frac{6}{9} = \frac{2}{3}
\]

Now set up the equation:

\[
\frac{x+6}{21} = \frac{2}{3}
\]

Cross-multiply:

\[
3(x+6) = 2(21)
\]

Simplify:

\[
3(x+6) = 42
\]

\[
x+6 = 14
\]

\[
x = 14 - 6
\]

\[
x = 8
\]

The value of \(x\) is 8.
