Question 778481
The top of a 25-foot ladder is sliding down a vertical wall at a constant rate of 3 feet per minute. When the top of the ladder is 7 feet from the ground, how far is the bottom of the ladder from the wall? 
----------------------
Draw the picture:::
You have a right triangle with
hypotenuse = 25 ft
height = 7 ft
base = "b" ft
------
b = sqrt[25^2-7^2)
b = sqrt(576)
b = 24 ft
