**Nat**, Thursday, July 15, 2010 at 2:28amDraw the problem out, with a ladder leaning against the wall, and label the respective lengths. You will notice it forms a right-angle triangle, with the ladder as the hypotenuse.

So the theorem is

a^2+b^2 =c^2

where c represents the ladder length (the hypotenuse), and so a can represent the distance of the ladder from the base of the building (the answer), and b is where the ladder reaches on the building.

Therefore,

a^2+32^2=40^2

Since a is what we need, rearrange the above formula to solve for a and you will get your answer. (Remember the units ft)
