How Do You Calculate Displacement for Different Motion Paths?

[claire.]

Hi PF! Okay so here's a problem I'm having trouble with.

A- A submarine dives 104 m at an angle of 28 degrees below the hor. . What are the two components (x & y)

B- A person walks 23 degrees north of east for 2. 38 km. How far woud another person walk due north and due east to arrive at the same location.

C- 5. A guy walks the path shown below. The total trip consists of four straight line paths.
Path 1 is 60.0 m due east.
Path 2 is 220.0 m due south.
Path 3 is 130.0 m 30.0° south of west.
Path 4 is 150.0 m 60.0° north of west.

Please helpp
