# physics need help!

I really need help on this Q, don;t know what to do with multtiple complex forces:
A jet plane is flying with a constant speed along a straight line, at an angle of 27.0° above the horizontal, as Figure 4.30a indicates. The plane has weight whose magnitude is 86500 N, and its engines provide a forward thrust of 103000 N. In addition, the lift force (directed perpendicular to the wings) is 77100 N and the air resistance is 63700 N. Suppose that the pilot suddenly jettisons 2550 N of fuel. If the plane is to continue moving with the same velocity under the influence of the same air resistance , by how much does the pilot have to reduce the thrust and the lift?
