Question
A ladder 10 ft long rests against a vertical wall. If the bottom of the ladder slides away from the wall at a rate of 1.3 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 8 ft from the wall? (That is, find the angle's rate of change when the bottom of the ladder is 8 ft from the wall.)

**Diagram Description:**

- The diagram shows a right triangle formed by the ladder, the wall, and the ground.
- The hypotenuse is labeled "10," representing the ladder, which remains a constant length.
- The horizontal side (ground) is labeled "x."
- The vertical side (wall) is labeled "y."
- There is a right angle indicated at the corner where the wall meets the ground.
- The angle between the ladder (hypotenuse) and the ground is shown in pink.

The task is to find how the angle between the ladder and the ground changes as the ladder slides away from the wall.
