How to find angle of elevation and depression with Calcuhubs Calculators

Use this calculator to calculate the angle of elevation where height and distance are given

Definition 

If, in Figure 1.1, BC represents horizontal ground and AB a vertical flagpole, the angle of elevation of the top of the flagpole, A, from the point C is the angle that the imaginary straight line AC must be raised (or elevated) from the horizontal CB; i.e., angle θ. See more math solved examples.

 

Example 1

An electricity pylon stands on horizontal ground. At a point 15 m from the base of the pylon, calculate the angle of elevation of the top of the pylon if the height of the pylon to the nearest meter is 50 m

Use this calculator to calculate the angle of depression where height and distance are given

Definition 

If, in Figure 2, PQ represents a vertical cliff and R a ship at sea, the angle of depression of the ship from point P is the angle through which the imaginary straight line PR must be lowered (or depressed) from the horizontal to the ship

 

Example 2

From the top of a vertical cliff 25.0 m high what is the angle of depression of a boat if the distance of the boat from the
cliff is 11.0 m
