In friction is it always true that coefficient of friction is tan theta? I have found a sum in HC versa part 1 work power energy sum no 43 where the angle of inclination is 37 degrees but mew is 0.5 which is obviously not tan 37 degrees. Please remove my particular confusion. (I would have liked to attach the image but cannot due to some technical issues. Sorry for inconvenience) I have gone through the solution and got it but here is the problem.

No, 
coefficient of friction is a property of surface at which friction force acts.
The formula you are talking about is the max. angle of inclination to which a incline plane can be inclined such that an object kept on it does not slides.
