Tan-1 3.09= 72.07 I've always been getting this as an answer but what gets me is when http://easycalculation.com/physics/classical-physics/resultant-vector.php gives you an answer of 3.9 degrees. I'm not quite sure what to think of my answer and their answer. Yes, the "head to tail"...

Following an example from a book that has a similar question, I replaced the values with the ones from this problem. Except it doesn't show how to solve the direction. I've tried a few triangles for calculations, if only I knew what the resultant triangle would look like, I think I could work...

The basics I suppose? (Close to nothing) I'm tackling this question that is way out of my level. I find it confusing, because with this http://easycalculation.com/physics/classical-physics/resultant-vector.php I've worked out the resultant force, but can't figure out the 'direction' except...

So how do you go about answering the "direction of the resultant force"?

So 3.09 degrees can be an answer with respect to the horizontal? By stating it is 3.09 degrees above the horizontal? I'm sorry but I don't quite understand what you stated. I'm not too knowledgeable with what I'm dealing here really.

The direction is (10 sin 34° + 90sin 76°)/(10cos 34°+ 90cos 76°) = 3.09 degrees? Does this answer the 2nd part of the question of "A body is acted on by two forces. Find the magnitude and direction of the resultant force by calculation"? So the magnitude is ticked at 97.66 N. The direction...

So it = 97.66 N? The resultant force? Now I need to find the direction.

Is this the possible equation? sqrt((10cos 34°+ 90cos 76°)^2 + (10 sin 34° + 90sin 76°)^2)

The angle between them is 42 degrees?

Yes, thanks for the pointer.

AC^2=AB + BC^2 I think?

Homework Statement A body is acted on by two forces. Find the magnitude and direction of the resultant force by using the mathematical method. I'm not sure if I've done this correctly, any pointers would be appreciated :) Also what is the angle between the two vectors? Is it 90 or 76 degrees...
