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?
2 answers

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

30222
