If: The Angle of Depression from Ed to the ship is 34 degrees. And the height of the cliff is 30m above sea level. How far out to sea is the ship?
-
The Angle of Depression from Ed to the ship will equal the angle of elevation from the ship to Ed as they are alternate angles.
Imagine the right anglede triangle formed by the cliff, the water and the line of sight from Ed to the ship.
From the ship the height of the cliff is the opposite side and the distance out to sea is the adjacent side.
Opp and Adj together means we use the Tan ratio
Tan 34 = 30 / x
x Tan34 = 30
x = 30 / Tan34
x= 20.235... (by calculator)
Hope that helps
Good Luck!
