We know that the tangent is always  perpendicular to the radius.

Therefore, we can say that the quadrilateral formed with ABOCA is always equal to 360^o.

and given BOC=130^o

and  we also know the angles between radius and tangent equal to 90^o

By calculating, we get:

360^o=90^o+130^o+90^0+BAC

BAC=360^o-90^o-90^o-130^o

BAC=50^o.
