A wall is 10 feet tall and is 15 feet from a house. A window in the house is 30.5ft above the ground. A tire escape slide attaches to the bottom of the window and to the top of the wall opposite the window. How long a slide must be purchased?

The vertical drop of the slide is 30.5 10 = 20.5 feet. The horizontal run is 15 feet. Use the Pythagorean theorem for the slide length, which is the hypotenuse.
This seems like a rather unsafe fire escape design to me. The slide is too steep.
