Sorry I attempted to delete it so I could move it to the maths section and deleted the text.
I'm still stuck with part ii even after help, I made two equations but got stuck as how to solve them.

From memory I believe they were

P sin a + 2.55g = R

Since you know the frictional force and mu, you know R
You also know g
When you have Pcosa and Psina you can divide so that you have tana
