Calculating Normal force of Incline on the Block

My problem is that I need to determine the normal force of the incline on the block.

The coefficient of static friction between the block and incline is mu^s = .295.

I have determined that the minimum value of "F" is 18.49 N.

I understand that "F" * sin (59.5) would be my answer to determine the normal force, yet I keep struggling on determining "F". Please help. The question is attached.
