The base of a 25-foot ladder is positioned 10 feet from the bottom of the building it leans against. An extension can be pulled out to make it a 30-foot ladder. How far does the base of the ladder, with the extension out, have to be away from the building to reach the same height as the ladder, without the extension, whose base is 10 feet away? * 1 point
