Question 180185
From an airplane flying at an altitude of 1000m , the angle of depression to a ship is 60 degrees. \The distance from the ship to a point directly below the plane is ?
----------------------------
Draw the picture.
You have a right triangle; find the base.
---------------------
The angle of depression from the plane = the angle of elemation from the ground.
---------------------------
tan(60) = altitude/base = 1000m/base

base = 1000m/tan(60) = 577.35 meters
