WebTo calculate degrees one takes the Arc Tangent of the slope: Degrees Slope = ArcTangent (Height / Base) NB. ArcView calculates slope as degrees What is important to understand is that we can measure the slope of any surface, defined by measures of topography, WebTo calculate the angle of the slope, divide the elevation change in feet by the distance of the line you drew (after converting it to feet). This is the tangent value for the angle of the slope. Apply an arctangent function to this value to obtain the angle of the slope (hit the ‘inv’ button and then the ‘tan’ button on most scientific calculators to get the slope angle).
