<PRE><B>Question 872311</B>
An airplane climbs at an angle of 11 degrees with the ground. Find the ground distance it has traveled when it has attained an altitude of 400 feet.
--------
Draw the picture.
You have a right triangle with 
base angle = 11 degrees
height = 400 ft
-------
tan(11) = 400/base
base = 400/tan(11) = 2057.82 ft
