1. A 56.2-kg high-school student hangs from an overhead bar with both hands. What is the tension in each arm if the bar is gripped with both arms raised vertically overhead?

2. What is the tension in each arm when the arms make an angle of 35.00 o with respect to the vertical?

I have two equations:

A.) sum of all forces=ma

B.) sum of all forces=0

i tried:

sum of all forces=56.2*9.81

but this was wrong

then for the second question i tried:

sum of all forces=56.2cos(35.00)

i found this equation after research and don't know too much about it.

I don't understand how to plug this into these equations or if the are the right ones. Could someone lead me in the right direction. any help would be greatly appreciated.
