Help! Answer all please

A barge is pulled by two tugboats. The barge is aligned horizontally while the rope of tugboat 1 is inclined with the horizontal 0-degrees upward, and rope of tugboat 2 is inclined with the horizontal 'a'-degrees downward. If the resultant of the forces exerted by the tugboats is a 6,261-lb force directed along the axis of the barge and 0=36 degrees, determine the magnitude of the tension (Ib) in rope 1 if a = 51° Answer in 2-decimal places only if applicable, and don't include units. A

Three children are standing on a 5 x 5-m raft. The weights of the children at points A, B, and C are 375 N, 260 N, and 400 N, respectively. If a fourth child of weight 425 N climbs onto the raft, determine where she should stand if the other children remain in the positions shown and the line of action of the resultant of the four weights is to pass through the center of the raft.
