This includes the azimuth, the direction of a celestial object from the observer on the Earth's surface, and angle of refraction, the process by which an angle deflects when it enters a medium, that are involved in the sextant's use. You can even account for other factors that may plagu...
the known distance from the house, and the angle between house and ground, simple geometry makes it straightforward to calculate the height of the house. Alternately, use a tangent table. Look up the tangent for the angle on the table and multiply that number by the length...

You can use this method to measure the angle between you and the top of that object, or the object's height.[11] 2 Measure the angle using the protractor. Keep the clinometer steady in that position, until the dangling string becomes still. Calculate the angle between the midpoint of ...
