Question 550682: A 20ft wire supporting a flagpole forms a 35 degree angle with the flagpole. To the nearest foot, how high is the flagpole? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A 20ft wire supporting a flagpole forms a 35 degree angle with the flagpole. To the nearest foot, how high is the flagpole?
-----
Draw the picture.
You have a right triangle with
hypotenuse = 20'
acute angle formed by hypotenuse and flagpole = 35 degrees
-------------
find the other side of the 35 degree angle.
----
cos(35) = flagpole/20
----
flagpole = 20*cos(35) = 16.38'
