A contractor leans a 23-foot ladder against a building. The distance from the ground to the top of the ladder is 7 feet more than the distance from the building to the base of the ladder. How far up the building is the ladder to the nearest tenth of a foot?

23^2=(x)^2 + (x+7)^2 x is the base distance.

solve for x.
so the base is 4.1? then i subtract that from 23?
math is important
