Here's how to get the resultant vector using the graphical method:
1) First, draw a cartesian plane so that it will be easy for you to place your directions and lines.
2) Then place the starting point at zero.
3) Use scaling to in your measurements.
4) Base your angle to the x axis.
5) Then connect your second vector to the first one.
6) Just follow the directions stated in the problem.
7) Then connect the endpoint of the last vector to the point of origin or zero.
8) Then measure it.
So that's it! That's the resultant vector. But you may not get the resultant vector accurately. It may just be close to the real answer because your not solving it, you just draw it. By just drawing it, there's a greater possibility to have an error. ;p
