Hello, can you please help me to solve this?

1. An airplane is flying at an air speed of 420km/h on a heading of 210. A 45-km/h wind is blowing from abearing of 50.Determine the bearing and ground velocity of the airplane using geometric vectors.

2. A pilot flies on a heading of 320 with an airspeed of 240km/h. Her actual ground velocity is 250km/h at a bearing of 318. Calculate the speed and direction of the wind.

3. A ship's course is set at a heading of 143 at 18 knots. A 10-knot current flows at a bearing of 112.Use Cartesian vectors to determine the result an tvelocity of the ship and its bearing?

4. A traffic light at an intersection is hanging from two wires of equal length making angles of 10below the horizontal. The traffic light weighs 2500 N. What are tensions in the wires?
