Final answer:
In aerial navigation, directions are given in degrees clockwise from north, called headings. To determine how far west of the airport the plane is, we need to know the specific heading.
Step-by-step explanation:
In aerial navigation, directions are given in degrees clockwise from north, called headings. Thus, due east is 90°, due south is 180°, due west is 270°, etc. A plane travels from an airport for 200 miles at a heading of ___.
To determine how far west of the airport the plane is, we need to know the specific heading. If the heading is due east (90°), then the plane would not have traveled west at all. If the heading is due west (270°), then the plane would have traveled 200 miles west. If the heading is between due east and due west, we would need to determine the angle between the heading and due west to determine the distance traveled west.
