A frame ABC is supported in part by cable DBE that passes through a frictionless ring at B. Knowing that the tension in the cable is 385 N, determine (a)- the resultant ( R) of the forces as a vector which exerted by the cables on the support at D and E, (b)- the angles between R and each of the coordinate axes.
