If a plane takes off on runway 31 (N 31o W) and flies 4 miles, then makes a right (90o) turn and flies 11 miles, what bearing will the traffic controller use to locate the plane?

After making the first leg, the plane is at

(-4sin31°,4cos31°) = (-2.06,3.43)

From there, the plane flies at W31°S,

moving another (-11cos31°,-11sin31°) = (-9.43,-5.67),

ending up at (-11.49,-2.24)

The bearing is W11°S
