traffic light is suspended at rest from two cables that meet at a point above the light. The left cable makes a

35^{\circ}

angle above the horizontal; the right cable makes a

55^{\circ}

angle above the horizontal. What is the magnitude of the tension in the right-hand cable? (Assume

g = 9.8\,\text{m/s}^2
