This is more for the Physics forum, but there's noone over there.
Three workers are pulling on ropes attached to a tree stump (S) as shown in the diagram.
Find the magnitude and direction of the resultant force on the stump.
Diagram is attached at the bottom.
A force of 60 Newtons North, a force of 35 Newtons East and a force of 40 Newtons 60 degrees South of East is applied.
I know the answer is 61 Newtons at a direction of 23 degrees North of East, but I'll be danged if I can get there.
A little nudge in the right direction would be helpful.
