ok so the problem wants me to find the tension in each cable, supporting the given load. not too bad of a problem...i have this triangle shaped object with the vertices at A B and C...to get the respected vectors, i call the side CA, U and the side marked CB, V. so there CA = Ucos 130 + Usin 130 and then CB = Vcos 30 + Vsin30, once i break these vectors into horizontal and vertical components i dont know how to solve for U and V...any help would be appreciated. thanks in advance.
