Now from the diagram; We need to resolve the force at point A into (3) components ; i.e x.y. & z directions which are equivalent to 
So;
= positive x axis
Negative y axis
= positive z axis
Then;

From equation (1); Let's make
the subject of the formula ; then :

Substituting the value for
into equation (2) ; we have:
