You can certainly find  tan-12  so I don't know what you mean.

Is this a part of a bigger question?

atan(22/11) = atan (2) = 63.434948822922º

Mmmmm.....looks perfectly valid, IMHO......(We're just asking ourselves, where does the tangent = 2 ??......Note that it has to be greater than 45º but < 90°)
