Two ropes A and B are attached to a mooring hook so that an angle o 60 exists between the two ropes. The tension in rope A is 80 lb and the tension in rope B is 120 lb. Use the parallelogram method to find the resultant force on the hook

The answer is this. but i dont know how to put it in a graph. should i start in north  east? or north west? 

Thank you

The following might help:

 

resultant

Use the cosine rule to get the length of the resultant:  \(c^2=a^2+b^2-2ab\cos\theta\)
