put this solution on YOUR website! A 13 feet ladder is placed 5 feet away from a wall the distance From the ground straight up to the top of the wall is 13 feet. Will the ladder reach the top of the wall?
The length of the ladder, the distance the ladder is from the wall, and the distance the ladder is "up the wall" ALL form a 5-12-13 right-triangle.
Therefore, the ladder will only get 12' up the wall. That's IT!
Am I missing something here? Where does the other person see this problem mentioning a window?
