imagine a triangle. The diagonal side is 17 ft. the bottom is 8 ft. Use the pythagorean theorem to find the third side. so

17^2 minus 8^2 = 225. then take the square root of 225, which is 15

**Ms. Sue**, Monday, October 4, 2010 at 9:55pmLet c = the length of the ladder. b = the distance from the wall. Use the Pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 8^2 = 17^2

a^2 + 64 = 289

a^2 = 225

a = 15

Btw -- I hadn't seen your post when a posted mine.
