Four forces are acting simultaneously on a sack: vectors

[VICKZZA]

Homework Statement

Four forces are acting simultaneously on a sack,Their magnitude are given as 200N.150N,175N,250N.THE ANGLE B/W 200N AND 150N IS 64DEGREE, AND B/W 150N AND 175N IS 59DEGREE AND B/W 175N AND 250N IS 74DEGREE.FIND THE RESULTANT FORCE ACTING ON THE SACK?

i need immediate assistance with explanation...

The Attempt at a Solution

 

[Doc Al]

Start by drawing a diagram showing the forces and the angles between them. I would arbitrarily put the first force pointing in the x-direction.

Are the forces pushing or pulling on the sack?

i am telling u a complete link about this question, its is from A level mechanics and the chapter is vector and its in the examples next to exercise 3a...page is 57.. please give me a detailed explanation

OK, so they give you the diagram. You can do as the book suggests, and add the vectors graphically. They give you that solution. Or you can use the method of components (that's what I would do).

Call the 200 N force to point in the x-direction. Now find the components of each force. Just add them up to find the resultant.

still not getting the answer u please resolve it urself and find the resultant force
