A sailor is being rescued using a boatwain's chair that is suspended from a pulley that can roll freely on the support cable ACB and is pulled at a constant speed by cable CD. Knowing that α=25° and β=15° and that the tension in cable CD is 80 N, determine
(a) the combined weight of the boatwain's chair and the sailor,
(b) the tension in the support cable ACB.
