A sculpture is suspended in equilibrium by two cables, one from a wall and the other from the ceiling of a museum gallery. Cable 1 applies a horizontal force to the right of

the sculpture and has a tension, Fn. Catble 2 applies a force upward and to the left at an

angle of 37.0° to the negative x-axis and has a tension, Fn. The gravitational force on

the sculpture is 5.00 '10`N. What is Fn?
