The image shows two triangles, with one inscribed inside the other. The triangles share an angle and have sides that are marked as proportional, suggesting the triangles are similar. We can use the property of similar triangles to solve for \( x \).

### Step-by-step approach:
1. **Identify the corresponding sides**:
   - For the large triangle:
     - One side is \( 12x - 8 \).
     - The corresponding base is \( 2x + 4 \).
   - For the smaller triangle:
     - The corresponding side is \( 16 \).
     - The corresponding base is \( 17 \).
  
2. **Set up a proportion** using the corresponding sides of the similar triangles:
   \[
   \frac{12x - 8}{16} = \frac{2x + 4}{17}
   \]

3. **Cross-multiply** to eliminate the fractions:
   \[
   (12x - 8) \times 17 = 16 \times (2x + 4)
   \]
   This simplifies to:
   \[
   204x - 136 = 32x + 64
   \]

4. **Solve for \( x \)**:
   \[
   204x - 32x = 64 + 136
   \]
   \[
   172x = 200
   \]
   \[
   x = \frac{200}{172} = \frac{100}{86} = \frac{50}{43}
   \]

So, the value of \( x \) is \( \frac{50}{43} \).
