ok i got my diagram posted question earlier
it wouldn't let me post anymore
I'm really sorry guys just trying to get my diagram to work =[

hey perfect ok...
so proof that the angles are equal...
I don't know

Ok there got it!!!!!!!!!

ok FBD ok object and gravity acting on it resolved into components

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

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!!!!!!!!!
