do 12 southwest first
distance north = -12 cos 45
distance west = 12 sin 45
now total north
distance north = 9 -12 cos 45 = .515
now total west
distance west = 7 + 12 sin 45 = 15.5
distance north = -12 cos 45
distance west = 12 sin 45
now total north
distance north = 9 -12 cos 45 = .515
now total west
distance west = 7 + 12 sin 45 = 15.5
