The Problem is ....
We Have no (Summation of Fx)
We Have no (Summation of Fy)
We Have no (Summation of Fz)
and Resultant Force (R)
That means we cannot solve "Direction Cosines" yet
But since the coordinates are already given
we can solve for Distance (A) from Origin
since we now have the Distances
we can now get their "Components of Forces"
ok we already have (Summation of Fx, Fy, and Fz)
we can now solve for their Resultant Force
