A crow sits on a clothesline midway between two poles as shown. Each end of the rope makes an angle of θ = 16° below the horizontal where it connects to the pole. If the combined weight of the crow and the rope is 8.4 N, what is the tension in the rope?

physics 
bobpursley,
assuming each side holds half the weight..
I see a triangle where sinTheta=(1/2weight)/Tension
sinTheta=(4.2N)/Tension
solve for Tension.
