Expert Answer:

Consider the figure .

angle of repose

The weight W can be resolved into two rectangular components. W cos f and W sin f. The component W cos f balances the normal reaction R while the component W sin f is equal to the limiting friction flimiting.

We notice that the angle of repose or sliding and the angle of friction are both equal.
