The system shown below is in equilibrium. Using the fact that block A is placed on a table, has a normal force of 40.2 N and it is not moving, what is the coefficient of static friction on block A?

I know you can't answer this but if you have any suggestions:

Calculate the tension of A in the string connected to block A. The mass of block B is 4.3kg and the mass of block A is 4.1 kg. The angle is 33 degrees.

THANKS SO MUCH
