[b] Vector A is 100m East at 0°, Vector B is 300m south and vector c is 150 meters southwest and vector D is 200 meters north west. There are two angle measurements given. I dont know how to upload the exact picture but if you go to http://ift.tt/1glYC3c and find the exact problem, the picture is on there as well as the answer. I dont know how they got to that answer. Please help.
Im not sure how to get the correct angle measurements for vector d. I tried to figure it out from the angles given but it was very confusing.
to find the resultant I did F_x=100+0+0+-75=25m
i got 569.6m
Where did I go wrong? I think it is the angle measurements I put in but Im not sure how to get the correct measurements.
