Question
a wall is 5 m. a ladder is leaning against it, which is 3 m. express the height from the top of the ladder above the ground as a function of how far the foot of the ladder is from the base of the wall.
3^2= base^2+ height^2
base= sqrt (9-height^2)
3^2= base^2+ height^2
base= sqrt (9-height^2)
