$T =\frac{W}{2~sin~\theta}$

Work Step by Step

We can consider the left part of the rope and the right part of the rope. The sum of the vertical component of the tension $T$ in each part of the rope is equal in magnitude to the crow's weight. We can find $T$: $T~sin~\theta + T~sin~\theta = W$ $2~T~sin~\theta = W$ $T =\frac{W}{2~sin~\theta}$
