Re: Angle the sun moves at sunrise or set
I can't access Facebook so I haven't seen your image, but a nifty little program called Stellarium (link below) might help you. Once you set the co-ordinates for your location, it shows everything in the sky in real time, and you can fast forward to see where everything will be later. I just looked at the sun setting in my location and it looks to be going down at about a 35 or 40 degree angle. Don't know if the exact angle can be determined, but I imagine it can be done.
It's open source so it's free, but best of all, it works. I've used it to see where the moon will rise and where the center of the Milky Way will be when the sun sets.
Hope that helps.
