LZ Hello
as shown in the figure, objects on the slope are subject to three forces, red is gravity, blue is slope supporting force, and black is wall pushing force. The reaction force of the black force is the pushing force of the object on the wall you asked
these three forces balance each other after the object stops
vertically g = f (blue) cos30
horizontally f (black) = f (blue) sin30
so
F (black) = g / cos30 * sin30
= gtan30
you seem to weigh by mass
that is 50x √ 3 / 3 ≈ 28.87kg
