"and to the top of the tall of the opposite window" What does this mean? – William Jul 3 '12 at 22:10
You posted your first question less than 1 hour ago; and you are already unhappy that you did not get answers as complete or as quickly as you wanted? We are not at your beck and call; try exercising some patience. – Arturo Magidin Jul 3 '12 at 22:18

Hint: the horizontal distance is 15 feet. The vertical distance is 30.5-10 feet. Time for Mr. Pythagoras.
