trouble with drawing vector diagrams.

1. The problem statement, all variables and given/known data
Total time 2min, duck travels 22 m 36degree N of E,then 65m E 25degree S.


2. Relevant equations



3. The attempt at a solution
i understand 36 N of E but what is E 25 degree S.

"E 25 degrees S" is the same as "25 degrees S of E": If "East" is to the right, then "E 25 degrees S" is at an angle 25 degrees below the horizontal. You can interpret "E 25 degrees S" as "first go E then go S until you reach an angle of 25 degrees".

Yes, it's just two different ways of writing vectors. It can be frustrating to new students of vectors. In my school, the math teachers write E25S but I usually write 25 S of E. I'm not sure which is better, sometimes I think I should just do it the way the math teachers do.
