# Math Help - resultant force

1. ## resultant force

Two forces of magnitude $100N$ and $70N$ act on an object. The angle between the forces is $120^o$. What is the resultant force?

i got $88.88N$ and $55.56^o$

correct?

2. Ok, I got the same magnitude, but different direction.

$\frac{sin\theta}{70} = \frac{sin(60)}{88.88}$

3. is it 43 deg?

4. Yep, that's what I got.
