I don't know how to approach this problem.

VP4.1.3 An eagle descends steeply onto its prey. Its weight (the gravitational force on the eagle), of magnitude 60.0 N, points downward in the-y-direction. The lift force exerted on the eagle's wings by the air, also of magnitude 60.0 N, is at an angle of 20.0 from the vertical (the + y-direction) and 70.0 from the +x-direction. The drag force (air resistance) exerted on the eagle by the air has magnitude 15.0 N and is at an angle of 20.0 from the-x-direction and 70.0 from the +y-direction. Find the x- and y-components of the net external force on the eagle, and find the force's magnitude and direction
