  When using Mercator projection one measures distances on  
 
  on the scale of Longitudes.
  indifferently on the scale of Latitudes or Longitudes.
  on the scale of Latitudes.
 

  A variation of 5W is indicated on the navigational chart. The helmsman affirms he is following a 135 course. What do I trace on the chart ?  
 
  140°
  130°
  135°
 

  After having calculated a course of 180 I want to give indications to the helmsman. The variation in the area is 10W. What do I tell the helmsman ?

  170°
 

  The variation of the area is to be found  
 
  in the compass rose on the navigational chart.
