A store sign is hung by two cables from post $\backslash ($ A B $\backslash ).$ The post is hinged at $\backslash ($ A $\backslash )$ and is supported by cable $\backslash ($ B C $\backslash ).$ It is desired to determine all forces acting on post $\backslash ($ A B $\backslash )$ by applying equilibrium to post $\backslash ($ A B $\backslash ).$ The tension in cable $\backslash ($ D E $\backslash )$ is $210$ N $,$ and the tension in cable FH is $157$ N $.$

Now that the components of the reaction force at $\backslash ($ A $\backslash )$ on post $\backslash ($ A B $\backslash )$ are known, determine the magnitude and direction of this force. For the direction portion of the force, determine the angle that the force makes in a counterclockwise direction from the positive $\backslash ($ x $\backslash )$ axis.

The magnitude of this force is N$.$

The direction of this force is
