<PRE><B>Question 1107076</B>
An airplane flies 120 kilometers from an airport in a direction of 210 degrees. How far west of the airport is the airplane then? How far south? In navigation, directions are given in degrees measured clockwise from north? 
-------------------
210 degrees for navigation corresponds to 240 degrees for trigonometry.
------
West distance = 120*cos(240) = -60 km (means 60 km west)
-----------------
South distance 120*sin(240) = -103.9 km (means 103.9 km south)
------------
