You just have to substitute values of slope and vertical distance in formula and get value of horizontal distance. Similarly, any one of them can be found if other two are given. For instance, if you have a slope given in Percentage as 10 % and a vertical distance of 50 feet, then equation will look like:
Divide the sum of your observations by the total number of observations made. For example, if you measured the horizontal angle between two objects daily for 30 days, divide the sum of those 30 observations by 30. Your answer will be the mean horizontal angle.epeat this process for the second object you are making a line of sight with. The difference between their azimuths is the horizontal angle. Repeat this step for each horizontal angle you wish to measure. Add up the relevant horizontal angles.
