Answer:

Let AB be A ladder and B is the window at 8 m above the ground C.

In right triangle ABC

By using Pythagoras theorem,

????????² = ????????² + ????????²

10² = 8² + ????????²

????????² = 100 − 64

????????² = 36

CA = 6m

Hence, the distance of the foot of the ladder from the base of the wall is 6 m.
