Answer 2

Answer:

62°

Step-by-step explanation:

BOA=126°

1) BOA+BOC=180°....(angles in linear pair)

126+BOC=180

BOC=56°

NOW

OB=OC...(Radius of the same circle)

therefore it is an isosceles triangle

therefore OBC=BCO=x

2)BOC+OBC+BCO=180°(sum of all angles of triangle)

56+x+x=180°

56+2x=180

2x=180-56

2x=124

x= 62°
