  1. Good grief, another correctly worded question! We are on a roll!
    Draw it on paper.
    The bearing of the airport from the plane is the same angle West of South as the plane is East of North from the airport.
    So where is the plane from the airport first
    tan angle East of North = 85 /120
    so plane bearing = 35.3 deg East of N
    so airport from plane is 35.3 West of South
    which is 180+35.3 = 215.3 deg Compass bearing clockwise from North
