A window repairman picks up one end of a large sheet of glass.A second smaller piece of glass is on top. Us=0.8 and Uk=0.2

A- What is the larges angle that he can tip the large sheet before the second sheet slips?

B- Once it starts to slide, to what angle must he lower the large sheet to stop the smaller one from slipping?
