Solving Physics Force Problems: Finding Resultant Force Components and Magnitude

[darealprince]

Homework Statement

Two forces, F_1 and F_2, act at a point. F_1 has a magnitude of 9.60 N and is directed at an angle of 61.0 degrees above the negative x-axis in the second quadrant. F_2_vec has a magnitude of 7.00 N and is directed at an angle of 53.7 degrees below the negative x-axis in the third quadrant.

1.) What is the x component F(x) of the resultant force?

2.) What is the y component F(y) of the resultant force?

3.) What is the magnitude F of the resultant force?

I have tried different methods but i think my approach is all wrong(mult. the degrees by the N) . does anyone know how to solve it?

This is a vector addition problem.

Resolve the vector into its x,y components and add to find the Resultant vector components. Then just transfer the answers.

$$\vec{F_1} + \vec{F_2} = \vec{F_{Result}}$$

sorry but as i said before i have no clue as to how to solve this problem i added the two forces to find part 3 but i got 16.6 which turned out to be wrong. I have a problem in seperating the forces into an x and y component. How exactly do you go about doing that when you are given a problem like this?

OK. Here you go. This should be helpful:
