1st step --> draw the diagram

2---> Look closely into it you would be able to see a right angel triangle with sides in familiar ratio of 3:4:5 and corresponding angles as 37,53,90.

3---> the triangle mentioned in (2) is triangle ABC ...C being the point where the two chains start

4---> Observe things closely you will get two equations

36cos(37) = T_2 cos(53)

cos(37) = 4/5 & cos(53) = 3/5

You will get your first answer

5----> Along Vertical

Mg = 36sin(37) + 48 sin( 53)

I wanted to attach the diagram

My MS paint isn't working so I tried to walk on Soroban's foot-print

and the result was as bright as coal but I would paste it here...don't keep laughing at it

angle CAB will be 37 degree

Angle CBA is 53 degree
