Answer with explanation:
The given vectors in are reduced to their componednt form as shown
For vector A it can be written as 

Similarly vector B can be written as

Hence The sum and difference is calculated as 

The direction is given by
 with positive x axis.
with positive x axis.
Similarly 

The direction is given by
 with positive x axis.
with positive x axis.
