Question 462669: a boat is 1000 meters from a cliff. if the angle of depression from the top to the boat is 15 degree, how tall is the cliff? round your answer to the nearest tenth. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! a boat is 1000 meters from a cliff. if the angle of depression from the top to the boat is 15 degree, how tall is the cliff? round your answer to the nearest tenth.
----
Angle of depression from the hill equals the
angle of elevation from the boat.
----
Draw the picture:
right triangle with bse = 1000 meters and elemation angle = 15 degrees
-----
Let the height of the cliff be "h"
Solve: tangent(15) = h/1000
---
h = 1000*tan(15) = 267.95 meters
