Can anybody explain the logic required to create an 82 degree countersink by requiring an input of 49 degrees?

Willing to bet most people would think that by inputting 41 degrees would create an 82 degree countersink...

Better yet, why can't we just input 82 degrees? Or 90, or 100 for that matter?

ha ha the robot wants us to do some math :)
The secret undocumented formula is: Sink Angle = 90 - (Head Angle / 2)
