When you resolve vertically you realise the only forces you need to consider are scostheta, R and W.
and when you resolve horizontally, you need to consider ssintheta and F.
then you solve for R and F, using part a values of theta and S
then use the formula friction = mu*normal
where mu is coefficient of friction.
Hope that helps
