(A) Given = 10N at 150 degree and = 20N at 290 degree. So the angle between the two vectors is,
The magnitude of resultant of these two vectors is,
The direction of the resultant vector from B is,
So the direction of the resultant from positive x-axis is,
So the resultant of and is 13.91 N at 262.49 degree.
(B) The head to tail diagram of the vectors is shown below.
