Those are common specs for 4X4's. They refer to the angle at which you can "approach" an obstacle (going forward) and not hit it or scrape. And "departure" is the same thing for the rear of the vehicle. So basically you could go from a flat level surface directly onto an intersecting surface of 38 degrees, and depart a 32 degree surface back onto a flat level surface without dragging anything. In the 4X4 world the higher the angles the better........
