Note, angle BOC is supplementary to angle AOB

 

So   AOB + BOC  = 180

 

So

 

67 + BOC  = 180

 

BOC  = 113

 

And angle BAC is an inscribed angle which intercepts the same arc as central angle BOC.......and an inscribed angle which intercepts the same arc as a central angle measures (1/2) of the central angle

 

So.....BAC  = (1/2)(BOC)   =  56.5°
