Angles of Elevation and Depression are used in measuring heights and distances in trigonometric applications using right triangles. These angles are made when we look up or down to view objects. Devices are available to measure angles of elevation and depression. These measured angles can be used in measuring heights and distance which are either tedious or impractical to measure, by modelling the situation into right triangles.
In the above picture a man standing on a cliff is simultaneously viewing an airplane flying in the sky and a boat sailing in the lake beneath. The angles of elevation and depression are marked as xº and yº respectively.
