Fx= Asin135+ Bsin75

I'm not sure what this lot is. ASin135 would invert the force and put it in the other direction.

Based on the image, the tension in CD is added to tension B to counteract force A.

From what I see (probably the long way around):

(((Tension in CD)Cos45)Cos[alpha]) + BCos[theta] = A

That would resolve the forces and give you equilibrium in the x plane, but I have doubts as per statement below.

However, if CD is applying a tension to the pole and forces B and A are directly opposing in the x plane, what is counteracting the y axis force exerted on the pole by the cable? Perhaps I'm overthinking it.

Please can you post the actual question, I feel something is missing.
