Well my scientific calculator is in my tool box but I do have my Machinery hand book and if I am looking at the charts right and my math is correct,you are looking at a slant range of 51.8 yards assuming 10' floors.This would require you to shoot with a sight setting of 34.4 yards to hit your intended target at a 45 deg angle from where you are if your peep height and sight length are the same as mine.This means you will hit exactly as far from the building as you are high in the air.
If the arrow is exactly at a 45 deg angle (starting out) and considering your arrow will drop 2.8 ft at 36.6 yards(11 stories)You should hit 33.8 yards from the building minus the affect of gravity which will be very minimal.So the answer is just over 33.8 yards.
This is as close as I can get with your info provided.
I don't know if it is right but it was fun trying to figure it out.I do suspect it is close.
