The top of a 12 foot long ladder is leaning against a wall with the top of the ladder 8 feet above the ground.The bottom of the ladder will be _______ feet from the base of the wall

Answer 1

pythagorean theorem!!

x^2 (leg 1) + y^2 (leg 2) = z^2 (hypotenuse = the ladder)

x^2 = (12)^2 - (8)^2
x^2 = 80
x = sq root (80) ~ 8.944
