Question

Trig: I have tried this problem several times, haven't figured it out

A plane is flying with an airspeed of 211 miles per hour with heading 248.7°. The wind currents are running at a constant 43.6 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

are you learning vectors?

Answer 2

not necessarily but this little part does speak about vectors... the main focus of the lesson is suppose to be law of cosine and occasionally sin
