How to set up this vector problem? Reading through my homework, I encountered this.  I don't know what a picture of this would look like, and how to decompose into separate vectors.  Once I figure out what I need to decompose into, I can do the rest.  Can you help me?

A car is driven east for a distance of 48 km, then north for 27 km,
  and then in a direction 32° east of north for 25 km. Determine (a) the
  magnitude (in km) of the car's total displacement from its starting
  point and (b) the angle (from east) of the car's total displacement
  measured from its starting direction.


Draw a picture. Piece by piece. Describing what it looks like just involves me repeating the problem. Draw a line segment right and label is 40. Draw a line segment up and label it 27, connected to the end of the previous line. Draw a line segment at an angle, label the degree 32 from upwards and the length 25. Then find the overall x and y displacement for the big triangle.
