You probably meant to ask:
"How far from the base should a 10ft ladder be placed so that it reaches 8ft up the wall ?"
solve for b
b^2 + 8^2 = 10^2

Since we know that the ladder is like the hypotenuse of a right triangle, we use the Pythagorous theorem. Which is what the person above used.
any Right (90 degree) triangle with height (a) and base (b) has a hypotenuse (c) where
a^2 + b^2 = c^2
