Sangle = tan-1(y / x) (1), Slope as angle for an elevation of 1 m over a distance of 2 m can be calculated as, Sgrade(%) = (100 %) y / x (2), Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as. A good foundation is essential for every house. Challenging to build on or use for outdoor activities. In this example you're given a rise of 2, you have to figure out what the run is, and youre given a 1:12 slope.
