Forces as a Vectors
Find the horizontal and vertical components of each of the forces:
f) 36N acting vertically
How do I find the value for the component if I cannot solve for ?
Find the resultant of each pair of forces acting on an object.
d) forces of 7N east and 12N north
=
°
Therefore, 13.9N, _____________ (How do I find the direction of this force? Can you please show me how using a diagram?)
e) forces of 6N southwest and 8N northwest
My Answer: 10N, N8°W  is my answer correct?
g) forces of 6N southeast and 8N northwest
My Answer: 2N, N45°W  is my answer correct?

You are overthinking it. The vector is vertical, hence it is acting entirely in the y direction. So the vector is (0, 36). (If you want, .)

Add them by components:
Using the usual xy coordinate plane, the first is (7, 0) and the second is (0, 12). So the resultant vector will be (7 + 0, 0 + 12) = (7, 12).
So the magnitude is and the angle (in the first quadrant, since the x and y components are both positive) will be 59.743562836 degrees. (Or 60. degrees N of E.)
