A ladder is resting against a wall. the foot of the ladder is 8 feet from the wall, and the top of the ladder is 19 feet from the ground. FIND THE slope of the ladder
without either the length of the ladder or the height of the wall, there's no way to tell.
If the top of the ladder is directly above a point x feet from the base of the wall of height h, all we know is that
h/8 = 19/(x+8)
