HINTS:
Part a) - Write down the position vector from A to B: rAB. The unit vector  from A to B is found by uAB =rAB/|rAB|. From this, the force of cable AB acting on the mast is: FAB = FAB*uAB.
Part b) -Worked out in a similar way, with AB to be replaced by AC.
Part c) - Refer to the lecture book for determining the direction angles and direction cosines directly from a unit vector that has been written in component form.

Please post questions here on the homework, and take time to answer questions posted by others. You can learn both ways.
