Looking for Pythagoras Review

One method for checking whether a wall is perpendicular to the ground involves a 10-foot pole. A builder makes a mark exactly 6 feet high on the wall, and rests one end of the pole at that mark. The other end of the pole rests on the ground. A triangle is formed. If the triangle is a right triangle, how far from the base of the wall is the bottom of the pole?
