An areoplane, coming in to land, passes over a point 1km away from its landing place on level ground.
if its angle of elevation is 15 degrees calculate the height of the plane in metres
:
Since we want the height in meters, change 1 km to 1000 meters
:
Use the tangent of 15 degrees, side opposite is the elevation (h), side adjacent is 1 km
Tan(15) =
h = 1000 * .26795
h = 268 meters
