    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 cos a = 6
    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
