Calculating angle with coefficient of static friction value!

Hi thank you for responding!

The mass of the box is 10kg. So the normal force here would have to be mg...?
No, the weight, W, is mg (98 N).

The normal force, N, is the normal component of the reaction force.

You find N by taking components in the normal direction (of N and W), and equating the sum to zero
what do you get?
