A sliding ladder. A 13-ft ladder is leaning against a house when it's base starts to slide away. By the time the base is 12-ft away from the house, the base is moving at the rate 5-ft/sec.
(diagram below)
1.) How fast is the top of the ladder sliding down the wall then?
2.)At what rate is the area of the triangle formed by the ladder, wall and ground changing then?
3.) At what rate is the angle X between the ladder and the ground changing then?
