50.0 kg stoplight hangs from wire over middle of an intersection. wire makes 15 degree angle with horizontal. find tension in each end of the wire

• physics -

well, assuming both sides of the wire support have the weight, then look at one side. Up= mg/2, and sinTheta=up/tension, or tension= mg/(2sin15)
