ANyone know how to draw a parallelogram/triangle to resolve force??

1. The problem statement, all variables and given/known data

http://www.xtremepapers.com/papers/...and AS Level/Physics (9702)/9702_s04_qp_2.pdf

question 1b

2. Relevant equations

3. The attempt at a solution
I drew a triangle using a scale of 1cm=1N. I drew (at least I think I did) a decent sketch with the help of the protractor and ruler. For the resultant length i Just connected the two ends of the 8N and 6N lengths(which gave me a triangle). I measured the resultant which gave me 5.1cm, which with my scale is 5.1N. But my answers way off. Am i doing it right?

I think my one was similar. Can you just sketch it out once, and tell me what you get? I think the mark scheme may be wrong.

You connected the wrong points. Make a parallelogram of the vectors, and show your drawing.

Kk i used a parallelogram this time, and got 13N thanks.

Splendid! It was the difference of the vectors what you got before.
