I do not know if you are extracting from a complete question because the question does not sound complete. It needs more context. IF the context is if an object begins to slide, or slides with uniform velocity on an incline with angle of inclination of 30 degrees, then the angle of friction is...... Notes: 1. Angle of inclination refers to the angle an incline makes with the horizontal. http://www.purplemath.com/modules/incldecl.htm 2. Angle of friction is the angle $\phi$ at which the coefficient of friction is $tan(\phi)$.
