A street light weighing 150N hangs from two wires as shown. One makes a 30 degree angle with the horizontal. The other makes a 45 degree angle with the horizontal. Find the tension in each wire.

(I have no clue please help!)

Try thinking of the force from each wire as the sum of a vertical component and a horizontal component (you may need some sines and cosines to do this). The object isn't moving, so all of these must balance: the vertical force from the two wires is equal and opposite to the force of gravity, and the horizontal components must cancel.
