ok this is a word problem it says A 24foot ladder is leaning against the top of a building the building is 15 feet tall. To the nearest foot how far is the base of the ladder from the building????

Using Pythagorean Theorem
15^2 + x^2 = 24^2
225 + x^2 = 576
x^2 = 351
the square root of 351 is 19 to the nearest foot

that means there's a trangle with legs x ( the thing you're trying to find, the distance of the base of the ladder from the building) and the wall (which is 15 feet). Then there's a right angle, and the hypotenuse is 24 ft. (the ladder)
so, using pythagorean theory,
15(squared)+x(squared)=24(squared)
solve it from there, it should be very simple.

its a triange, so you use pythagorean theorem, so its 15squared + xsquared = 24 squared...then solve for x!
