Trig question please help.

Question

A plane is flying with an airspeed of 211 miles per hour with heading 272.7°. The wind currents are running at a constant 42.2 miles per hour in the direction 238.6°. Find the ground speed and true course of the plane. (Round your answers to the nearest whole number for the speed and to one decimal place for the angle.)

Answer 1

Draw and label a diagram!

The angle between the plane at the air current is 87.3°

Use the Law of Cosines to determine the resultant speed.

Use the Law of Sines to determine the heading/bearing.
