the sum of the forces in the x direction is $24.1$ Newtons.

#### Explanation:

The horizontal forces in this situation will be the force of friction (a negative force) and the horizontal component of the applied force.

By trigonometry we see that

F_(A"horizontal") = 28cos(12˚) = 27.4 N

You should subtract the force of friction from this. Therefore, the net horizontal force will be $27.4 N - 3.3 N = 24.1 N$.

If you knew the mass of the tourist you could find the acceleration from this by dividing the net force by the mass (since f_"net" = ma)

Hopefully this helps!
