Do vector resolution to get C. 
Look at force at B it's giving a clockwise rotation to A.
Hint: clockwise rotation -
        Anticlockwise rotation +

yeah i did that the sin and cosine of 52 then multiply by 100

Okay, these are force vectors acting on the beam, they are free vectors, meaning, we can create one resultant force equivalent to the sum of the original forces, and apply this at one pt. on the beam. But when we do this, we also have to account for the moment that will be produced.
