vector components?
(a) Using graphical methods, find the vector sum A + B.
Magnitude of A + B:
___________
Direction of A + B:
___________° counterclockwise from +x-axis
(b) Using graphical methods, find the vector difference A – B.
Magnitude of A – B:
_________units
Direction of A – B:
_________° counterclockwise from +x-axis
For the magnitude I got 5.167 and it came up as the right answer. However I am having trouble calculating the direction……can someone please help?? also how do you subtract vector components; how is it different from adding them? Thank you!

As for subtracting vectors, it’s the same as adding them except you reverse the direction of the vector being subtracted. By definition.
A – B = A + (-B)
and -B is the vector with the same magnitude as B but a direction 180 degrees away. In your case, since B is 8 units along the negative x-axis, -B will be 8 units along the positive x-axis.
