Take the friction coefficient and multiply by Tan^-1.(2nd function tan^-1 key on your calculator)
Note:the angle of repose is not affected by the weight of the body.
EX.A body that weighs 50Lb is placed in contact with a  inclined plane surface. The coefficient of
friction between the surfaces is .25. The angle between the inclined surface and a horizontal reference plane is 28 degrees. The tangent of .25 to the negative 1 power is 14 degrees.
