Question 1162140
.
<pre>

Calculate all x-components of the four forces, and then add them. You will get Fx.


Next, calculate all y-components of the four forces, and then add them. You will get Fy.


Then the magnitude of the resulting force is  {{{sqrt(Fx^2 + Fy^2)}}}.


Its direction you will find from  tan(a) = {{{(Fy)/(Fx)}}}.

Happy calculations (!)
