How to Draw a Force Diagram for an Object Suspended by Strings?

Click For Summary
To draw a force diagram for a 5 kg object suspended by two strings at a 52° angle below horizontal, it is essential to identify the forces acting on the object. The weight of the object, which is 49 N (calculated using gravity), acts downward. Each string exerts a tension force at an angle of 52° from the horizontal, which must be resolved into horizontal and vertical components. The vertical components of the tension forces must balance the weight of the object, while the horizontal components must cancel each other out. Ensuring these forces are accurately represented will confirm the correctness of the force diagram.

What is 90 - 42 ?

I meant to put 52° so 90 - 42 would be 38°. I was wondering if my force diagram was correct.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
