A contractor is required to prepare a soil surface so that its planar and the normal direction to the surface is within .5 degree of vertical. If the elevation points A and B, relative to the elevation at point c, are -3.3ft and -4.3 ft, determine the angle between the soil surfaces normal direction and the vertical, and if the surface is sufficiently level.
