Frictional force on 43 kg block at rest on 19° incline

[grouchy]

a block is at rest on the incline shown in the figure. the coefficients of static and kinetic friction are s = 0.42 and k = 0.36 respectively. The acceleration of gravity is 9.8 m/s^2. the angle of inclination is 19 degrees.

what is the frictional force acting on the 43 kg mass? answer in units of N.


Honestly I have no idea what to do on this problem...

If the block is at rest, you need only to identify all the forces acting on the block and apply Newton 1 to solve for the unknown friction force.
