- Trigonometry law of cosine -
**bobpursley**, Monday, April 7, 2014 at 4:03pmdraw the diagram. Add the wind vector to the speed vector (head to tail). The resultant from the origin to the head of wind is now the resultant. Label it R.

You have two sides, and the angle between S and W. Figure it out. I see it as in my head as the 360-30-175 =155 check that.

R^2=200^2 + 30^2 - 2*200*30Cos155

grab your calculator, and find R
