Question 272686
.
A boat is 1000 meters from a cliff. If the angle of depression from the top of the cliff to the boat 
is 15 degrees, how tall is the cliff?
~~~~~~~~~~~~~~~~~~~~~~~~~~~



        The solution in the post by @mananth is fatally wrong.

        I came to bring a correct solution.



Angle of depression = 15 degrees
The sides containing the right angle
One side is the distance and the other side is the height
tan(15°) = height / distance from cliff
tan(15°) = height / 1000
height = 1000 * tan(15°)
= 1000 * 0.26794919243
267.95 meters is the height  (rounded).    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>ANSWER</U>


Solved correctly.
