(6-2)(180)/ 6  =  (3/4) 180 =  135  = BAD           Agreed; it's BAD!cheeky

----------------------------------------------------------------

Angle BAC = 120 - 108 = 12º laugh

Interior angle of  tegular  hexagon =   (6-2)(180)/ 6  =  (2/3) 180 =  120  = BAD

Interior aangle of regular pentagon  =  (5-2) (180)/5 =  108  = CAD

 

BAC  =  BAD - CAD  =  120  -  108   =   12°

 

Corrected  !!!
