# Resultant force direction

1. The problem statement, all variables and given/known data
A 33 N force acts on an object at 30 degrees West of South while a 17 N force acts on the same object at 30 degrees North of West. What is the resultant force and direction.

Force1= 33 N
Force 2= 17 N

2. Relevant equations

Force diagram? Cos?

3. The attempt at a solution

I've been looking forever on the internet, in books but I really have no idea on this. I've tried stuff with cos and sin, though...But nothing worked...I know the answer is 37 N @ 57 degrees west of south. This is new material in my class so this is the first time I've tried to work a problem like this. I have no clue what to do!

Are you comfortable with how to add vectors?

I found force using Pythagorean, but still trying to find direction

Use triangle law of vector addition or better still use the parallelogram method whose diagonal tells you the direction of the resultant:p\

HINT: THE MAGNITUDE OF FORCES IS NOT IMPORTANT AT ALL....
