Cаlculаte the nооn Sun аngle at 300 Nоrth latitude on a day when the Sun is directly over the latitude 23.50 South. Work it like this. 900 - the Sun's angle at your location = how far away in degrees you are from the noon Sun. And, if the Sun is at 23.50 South and you are at 300 North, then you are (23.5+30=) 53.50 from the noon Sun's location. That gives 900 - the Sun's angle at your location = 53.50. Solve for the Sun's angle at your location.
