The image shows two trapezoid-like shapes, and the task is to find the scale factor between them.

To find the scale factor between two similar shapes, we can compare the corresponding sides. In the larger shape, one side is labeled as 15, while the corresponding side in the smaller shape is 10. Another corresponding pair is 9 in the larger shape and 10 in the smaller shape.

### Step 1: Compare the corresponding sides
We have two corresponding side lengths:
- Larger shape's side: 15, Smaller shape's side: 10
- Larger shape's side: 9, Smaller shape's side: 10

### Step 2: Calculate the scale factors
- For the first pair of sides:  
  \[
  \text{Scale factor} = \frac{10}{15} = \frac{2}{3} = 0.6667
  \]
  
- For the second pair of sides:  
  \[
  \text{Scale factor} = \frac{10}{9} = 1.1111
  \]

### Conclusion:
The first side pair (15 and 10) suggests a scale factor of \( \frac{2}{3} \), while the second pair (9 and 10) gives a scale factor of approximately 1.111. Since the scale factors are not consistent, the shapes may not be perfectly similar, meaning they don't maintain proportionality across all sides. However, if you are specifically looking for a scale factor based on certain sides, you can use the one you prefer, depending on which dimensions are relevant for your comparison.

### Tip:
Always ensure that all corresponding sides are proportional when verifying similarity between shapes.
