Thanks for the help guys!!!
I really appreciate it!!!

ok I drew the thing as caerfully as I good

h t t p : / / i m g 3 7 . i m a g e s h a c k . u s / i m g 3 7 / 7 8 0 7 / f i r s t d w s . j p g

ok I redrew it chekc it

Ok I followed the directions and made a line through the point of the force of gravity parallel to the slope of the ramp...

walla I noticed a theta that I thought the triangle was and thought it was equal to the angle the ramp makes with teh surface it sits on as it would appear to be but I don't know how to prove it...

ok the problem with this triangle is...

well the hypotenuse is the force of gravity which it is suppose to be

but the opposite side is y component of the force of gravity is the opposite of this triangle when it's suppose to be the adjacent...

sigh I still don't see the other triangle were the hypotenuse is the force of gravity with the opposite is the is the x component of the force of gravity

THANKS!!!
