A big brass lantern hangs from three chains as shown below. The chain C1 is at an angle of 50.0 deg below the horizontal, while the chain C2 makes an angle of 60.0 deg with the vertical. These two chains join at knot K and the lantern hangs from the vertical chain, C3. If the lantern has a mass of 55.0 kg, find the tension in chain C1.
i got c1= 474, by doing c1 sin50 +c2sin30=55(9.8)
and c2sin60=c1sin40 solve thro system of equations...
but its wrong haha
