A 13 foot ladder is leaning against a wall. If the point where the ladder meets the wall is 12 feet above the ground, how far from the base of the wall is the the ladder?
I would use the formula a^2 + b^2 = c^2 so your problem would look like this: 12^2 + b^2 = 13^2 144 + b^2 = 169 subtract 144 from both sides b^2 = 25 find the square root of 25 b = 5
