Challenge #67: Calculate Spatial Angles

[Ruud]

My solution.

Solution attached. @Aster I too encountered an inconsistency with my formula based solution. See the spoiler for more details.

I used the ACOS function and got 31.55 vs. 31.61 using ASIN. In the solution I was that the distance for all three sides were calculated, so I added two more formulas. ASIN, ACOS and ATAN return a different result in degrees.

The spatial version was quite simple, i struggled with non-spatial one. I completed it, though, and learned a trick or two in the process.

I feel like I solved this too quickly.

That challenge takes you down memory lane.

I must admit that the DirectionDegree is a bit confusing and the supporting page is not much helpful. I could just see that it could match if I subtracted it from 90. It also matches the NorthEast direction.The Trigonometry was fun is revisit. It don't get an exact match, close enough to believe that the precision has changed in the tool.
