A ladder is in a safe position if the height it reaches on the wall is four times the distance of the base from the wall. To the nearest tenth of a foot, find the length of the following ladder. The ladder must reach a 16foot height.

pythagorean theorem.....if the height is 4 times, and it must reach 16, then the distance along the horizontal must be 4. so 4^2 + 16^2 = c^2. where c is the length of the ladder. Use a calculator to solve.
