Answer 1

To determine the height of one stair, we need to consider the dimensions given in the drawing. The values "9 in" and "15 in" likely refer to the run (the horizontal part of the stair) and the rise (the vertical part of the stair) respectively.

If "9 in" is the run and "15 in" is the total height of the stairs, the height of one stair (or the rise) can be calculated based on the total height divided by the number of steps. However, without additional information, this isn't specified.

If we make an assumption that "15 in" represents the total height of the stairs and there are typically a certain number of steps (like 12 in standard stair design), we could calculate it out:

Using the design of stairs, a common height for each riser is around 7" to 8", but we don’t have the exact number of stairs.

For just choosing one of the responses, the most reasonable answer listed is:
- **12 in.**

This would represent a typical stair rise.
