I have a qns whereby a ramp of mass M rests on a frictionless floor and a mass m rests on the ramp, with no friction in between the mass and ramp. I need to find the acceleration of ramp M and mass m.

I have the answers but I don't really understand them.

aM= 2mgsinxcosx/M+m(sinx)^2 . I don't understand why is there a msin^2 term here

am=[(M+m)gsinx]/M+(msinx)^2 . Again I don't understand why is there a msin^2 and how does M factor into the acceleration.

Can someone pls teach mr how to get the ans?
