I need help setting this problem up. A force of 36lb is required to hold a 70lb toolbox on an incline. What angle does the incline make with the horizontal?

need to know mu, friction coef
if there is no friction, let mu = 0
F - mu (70) cos A = (70) sin A
if mu is zero then
F = 90 sin A
so
sin A = 36/90
