A more simple diagram for the given problem can be drawn as
In this diagram i have designated two force vectors as A (having magnitude 800 N)and B (having magnitude 400 N).
Now, from the figure, we can write
or,
or,
And
or,
or.
So, the resultant force (F) will be
or,
or,
Now the magnitude of resultant force (F) can be calculated as
And the direction () of resultant force can be calculated as
Hence, the resultant force is making an angle of nearly 220 with positive x - axis in clockwise direction.
For any doubt please comment and please give an up vote. Thank you.
