where A and B are the sides of a triangle and C is the triangle's hypotenuse.
The 17 foot ladder in this situation is your hypotenuse, and you have one side of the triangle: 15.

15 squared = 225
17 squared = 289
solving for b squared, we get 
taking the square root of 64, you get 8 feet, the distance between the house and the base of the ladder.
