It feels like a better puzzle when the answer comes out nice and simple. 

Yeah, i also usually prefer the ones that simplify nicely. Also because it's an indirect confirmation one is on the right track.

I don't think it simplified nicely, which isn't surprising when you put stuff like that into an inverse cosine.

[Daily puzzle] Find the radius of the circle

I'm not as much of a fan of these brute force calculations, but once I start on something I find it very hard to stop...

I gave myself 15 minutes to do this, and I thought I had it, but it turns out I made a mistake. Ended up spending maybe 30-40 minutes on this problem... not great for my productivity today lol
