Finding Angles 1 & 2 in Fig. 4-51

[Miike012]

Find the angles '1 and '2 in Fig. 4–51 if all the weights
are at rest.

Solution: The picture is on the paint document... I also drew some diagrams to help solve the problem.. I wanted to know if the diagrams were correct? Anyways as I proceed to solve for angle 1 and 2 it is hard because I don't know how to pull all the information together...

i think your diagrams are correct. Now system is at rest so all the forces acting in opposite directions are equal.
