A stadium for sporting events is constructed with a partial roof covering the seating arrangements. One

of the many supports for the roof is shown in the figure below. The structure is rigidly fixed to the

ground at point $A.$ The vertical portion $AB$ is $H=70m$ long, the inclined portion $BCD$ makes an angle

of $=45$ from the horizontal, and the horizontal distance from point $B$ to point $D$ is $L=20m.$ The

applied loads can be modeled as a single concentrated force of $F=47kN$ at point $C,$ which lies

midway between points $B$ and $D.$ Also, the force $F$ acts perpendicular to section BCD$.$ Neglect the

weight and thickness of the structure for this analysis. Determine all support reactions at point $A.$

Note: Express your answers following the standard sign convention for the coordinate system shown.
