Similar to an angle of elevation, an angle of depression is the acute angle formed by a horizontal line and an observer's line of sight to an object below the horizontal. A pilot is flying over a straight highway. He determines the angles of depression to two mileposts, 6.2 km apart, to be 32° and 44°, as shown in the figure below. Find the distance of the plane from point A to the nearest tenth of a kilometer. km A 44° B
In order to estimate the height of a building, two students stand at a certain distance from the building at street level. From this point, they find the angle of elevation from the street to the top of the building to be 39º. They then move 270 feet closer to the building and find the angle of elevation to be 50°. Assuming that the street is level, estimate the height of the building to the nearest foot. ft
