A 13-ft ladder is leaning against a house when its base starts to slide away. By the time the base is 12 ft from the house, the base is moving away at the rate of 5 ft/sec. a. What is the rate of change of the height of the top of the ladder? b. At what rate is the area of the triangle formed by the ladder, wall, and ground changing then? C. At what rate is the angle between the ladder and the ground changing then? 13-ft ladder X(t) a. The rate of change of the height of the top of the ladder is t/sec. (Simplify your answer.)

![**Educational Exercise: Ladder Sliding Problem**
A 13-ft ladder is leaning against a house when its base starts to slide away. By the time the base is 12 ft from the house, the base is moving away at the rate of 5 ft/sec. Answer the following questions:
**a.** What is the rate of change of the height of the top of the ladder?
**b.** At what rate is the area of the triangle formed by the ladder, wall, and ground changing then?
**c.** At what rate is the angle between the ladder and the ground changing then?
**Diagram Explanation:**
- A right-angled triangle is formed by the ladder, the wall, and the ground.
- The hypotenuse is the 13-ft ladder.
- The base of the triangle is labeled "x(t)" and represents the distance from the wall.
- The height is labeled "y(t)" and represents the height from the ground to the top of the ladder.
- The angle between the ladder and the ground is labeled θ (theta).
**Solution Box for Part (a):**
The rate of change of the height of the top of the ladder is [_____] ft/sec.
