You can put this solution on YOUR website! An airplane travels 150km/h for 2 hours at 138 degrees from Omaha. How far south is the plane from Omaha after those two hours?
------
Note: I'm assuming zero degrees is due North from Omaha so the
trig angle followed by the plane is really -48 degrees (4th Quadrant).
--------------------------------------------------------------
Draw the picture.
The plane has gone 2*150 = 300 km
---
The south component of its flight = 150cos(-48) = 150*0.6691 = 100.37 km
