    can you post it to a website, then post the link here as

    w w w . p i c. c o m

    let me know if you still don't understand what I'm trying to say

    ok in order for you to say that

    Force of gravity y component equals
    Fg cos theta

    and

    force of gravity x component equals Fg sin theta

    angle one and angle two and angle three have to be equal to each other because we use the angle of the ramp that it makes with the surface it sits on in the equation because we assume that angle 3 is equal to angle 2 and angle 1 which allows us to write

    Fgx = Fg sin theata

    Fgy = Fg cos theta

    ok I don't want to assume that angle 1 and 2 and 3 are equal to each other

    I would like to see the proof

    THANKS A BUCNH!!!!!!!!!
