The given image contains a right triangle and another smaller right triangle inside it. To solve for the unknown length \(x\), we can approach it using geometric relationships, likely similar triangles or the Pythagorean theorem.

### Steps to solve:

1. **Identify two right triangles:**
   - The larger triangle has a height of 9 and a hypotenuse of 10.5.
   - The smaller triangle, sharing the same angle as the larger one, has a hypotenuse of \(x\) and a base of 3.5. Since they share the same angle, the two triangles are similar.

2. **Set up the ratio of corresponding sides** (since the triangles are similar):
   The ratio of the sides of the larger triangle to the smaller triangle must be constant.

   For the larger triangle:
   - Height: 9
   - Hypotenuse: 10.5
   
   For the smaller triangle:
   - Base: 3.5
   - Hypotenuse: \(x\)

   By similarity:
   \[
   \frac{9}{3.5} = \frac{10.5}{x}
   \]

3. **Solve the proportion:**
   \[
   \frac{9}{3.5} = \frac{10.5}{x}
   \]
   Cross-multiply to get:
   \[
   9x = 3.5 \times 10.5
   \]
   Simplifying:
   \[
   9x = 36.75
   \]
   \[
   x = \frac{36.75}{9} = 4.083\ (\text{approx.})
   \]

So, the length of \(x\) is approximately 4.083 units.
