Refer to this list for the coefficient of friction, then plug it into the derivation of the maximum angle.

Without coefficient of friction, the problem is not complete.

Wtf!!! How do we know the coeff of friction?!?! ;(

From the list it is given as 0.6 0.6 , which is specific, because when certain substances in certain conditions come in contact, a coefficient of friction is defined.

the "simple derivation" referred to in the question is tan x=coefficient of friction.thus, x=tan inverse of the coefficient i.e.0.6(as in the list)
