Angle of Elevation
Angle of Elevation: the angle to which an observer would have to raise their line of sight above a horizontal line to see an object
Angle of Elevation
Angle of Depression: the angle that an observer would have to lower their line of sight below a horizontal line to see an object
Angle of ElevationA surveyor stands 200ft from a building to measure its height with a 5ft tall theodolite. The angle of elevation to the top of the building is 35°. How tall is the building.
Angle of DepressionAn airplane is flying 3500 ft above the ground and begins a 2°descent to land at an airport. How many miles from the airport is the airplane when it starts its descent?
