static on inclined planes

a mass of 46 kg rests on an smooth inclined plane at 38 degrees to the horizontal. It is supported by a rope held horizontally. Find the tension in the rope and the reaction of the plane on the mass.

Re: static on inclined planes

Hello, nice to meet you.

we have : 0B9pGxyM9yy2fMDlkNmJhMjUtZjc0Ny00NzIwLTk1NTYtYmNkYWQ2MWMzMWI5?nonce=585d88i8ol070&user=16490768842354261273&hash=i6vbbl6dcuce1oesbpmjo8r4pbd57cjl

=> : Rcos(a)=P=mg => R=mg/cos(a)
and T=Rsin(a)=mg*tan(a)

m=46kg, g~9.81 kg*m/s^2, a=38°
