    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?

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

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