A person holds a 3.0 kg block against a rough wall by pushing the block diagonally at an angle of 32 degrees with the horizontal. If the coefficient of friction between the block and the wall is 0.782, determine the smallest amount of force with which the person must push in order to hold the block stationary.

A person is pushing against a wall while their body is slanted.
The wall is made of smooth ice, therefore it has zero friction. The
floor, however, is made of rough sandstone and as a result, has
coefficients of friction
