Calculating Force on a Slightly Angled See Saw - Simple Lever Question Explained

[bunion]

Hi, if you have a see saw with equal weights on each side, but it is at a slight angle; how do you calculate the force in Newtons on one side which is making it balance?

Please see the picture:

Does the slight angle make a difference?

Hint: If the 50 Kg mass is in equilibrium, what force must the lever exert on it?
