A light air craft takes off flying die north then turns and flies 11 000 metres due west.The plane then has a bearing of 340 degrees from its starting point.For what distance did it fly due north?

Answer 1

the plane has a heading of 340°, not a bearing.
If they are heading toward a lighthouse on that heading, the lighthouse has a bearing of 340°

If the plane flies x meters due north, then

11000/x = tan 20°
x = 30222

Answer 2

30222

Answer 3

4, 003.7m
