Question 1120574
--------------------------------------------------------------
From the top of a hill, the angle of depression to a house is measured to be 17o.   If the hill is 40 feet tall, how far away is the house from the base of the hill? 
------------------------------------------------------------



Angle of elevation from house to top of hill, also 17 degrees.  Base of the hill is where angle of 90 degrees is.


{{{40/x=tan(17)}}}


{{{x/40=1/tan(17)}}}


{{{x=40/tan(17)}}}


{{{x=130.83*feet}}}
