Since you don't know the directions of the reactions you just guess on the direction. If you get a negative answer then that means your guess is wrong and the force (or moment) is in the opposite direction. Let me know if that doesn't answer your question.
I am very happy to see the vidoe after you give this Analysis of a rigid body in 2D in statics equilibrium.
