Force and Motion, I'm a bit confused on how to approach this.

1. The problem statement, all variables and given/known data
Two forces, F1 and F2, act at a point. F1 has a magnitude of 8.60 N and is directed at an angle of 63.0 (DEGREES) above the negative x axis in the second quadrant. F2 has a magnitude of 6.00 N and is directed at an angle of 53.2 (DEGREES) below the negative x axis in the third quadrant.

What is the x component of the resultant force?

What is the y component of the resultant force?

What is the magnitude of the resultant force?

2. Relevant equations



3. The attempt at a solution

What equation should i use?

I was thinking of using the equations that i used to break velocity up into x and y components:

VCOS(ANGLE)

so anyways...

the y component i was thinking:

(8.6^2) + (30) = c^2
Where the root of c^2 would give me the y-component?

I am a little lost any help would be appreciated. Thanks!

I figured it out. :)
