i have drawn FBD and labbelled all of the forces and tried to solve for alpha using simultaneous equations and other methods (the names of which I am not too sure). could anyone please tell me what to do next?

much obliged

50-F-1250sinaplha=0

f=ma perpendicular to slope

N-1250cosalpha=0

F=mu*N

mu=0.1

N=F/mu;N=10F

; 10F-1250cosalpha=0

F+1250sinalpha=50

ps, I am half asleep so excuse any blatant stupidity
