Challenge #67: Calculate Spatial Angles

[jarrod]

hmm... getting a different answer by using trig calcs... very close, so i'm assuming it isn't taking curvature into account or something silly like that???

Think I used a bit of spatial and trig. I created all the points then just found the distance/angle with trig. Think I had to convert from radians to degrees so maybe that's why I'm off .05 degrees.

I never would have been able to do the mathematical approach off the top of my head. Attached is the solution using spatial tools.

I will admit that this challenge went way over my head (at some sort of calculated angle) and I had to go to solution for help.

Done with a mixture of spatial and trig first (could be easily converted to formulas) then simplified to pure spatial. Hadn't realised that radians not degrees were the default for trig formulas.

My solution.

about Bonus question:
I calculate them as a points on the surface of the sphere(r=6378.137km)
