Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I would like to solve this problem.

Pulley is attached to the green rope that is 2' long.

The weight is 1 unit.

a and b are unknown.

The green rope's point of attachment is 20' higher than that of the blue rope.

The distance between two walls is 20'.

I would like to solve this for the forces in the green rope and the angle the green rope is making with the wall.

I am not sure how to proceed.

Thanks.
