The x-component of the normal force is equal to 1706.45 N.
Why?
To solve the problem, and since there is no additional information, we can safely assume that the x-axis is parallalel to the hill surface and the y-axis is perpendicular to the x-axis. Knowing that, we can calculate the components of the normal force (or weight for this case), using the following formulas:

Now, using the given information, we have:

Calculating, we have:


Hence, we have that the x-component of the normal force is equal to 1706.45 N.
Have a nice day!
