If Force 1 and Force 2 are in the opposite direction the magnitude of the forces are subtracted. (i.e. Force 1's direction = 0 degrees, and Force 2's direction = 180 degrees)

Static (standing still):
mg sinθ > μs mg cosθ tanθ >μs
Kinetic (moving):
θ > 21.8° movement begins when angle of the incline is greater than 21.8
