He provides courses for Maths, Science, Social Science, Physics, Chemistry, Computer Science at Teachoo. It is used in the formula to calculate the ratio of distance to height, which is then used to calculate the angle of depression. To calculate their height above the ground, the balloonists simultaneously measure the angle of depression to two consecutive mileposts on the road on the same side of the balloon. This relationship is reflected in the formula, where the height and distance are used together to calculate the angle of depression. Putting the values of height and horizontal distance in the above formula: $$ \text{Angle Of Elevation} = arctan(\frac{2}{1}) $$, $$ \text{Angle Of Elevation} = arctan(2) $$, $$ \text{Angle Of Elevation} = 63.434^{} $$.
