The pilot of a helicopter measures the angle of depression to a landing spot to be 18.8 degrees. If the pilot's altitude is 1640 meters, what is the horizontal
the angle of depression to a landing spot to be 18.8 degrees.
If the pilot's altitude is 1640 meters,

Tan 18.8 = height/ ground distance
ground distance = height/tan 18.8
=1640/tan 18.8 degrees
=4817.46
=4817 meters
