Question

pls explain with step by step​

Answer 1

Answer:

BOC=66 and AOC=120

Step-by-step explanation:

in the figure COB and AOC are two isosceles triangles with OA=OC =radius and OC=OB

so OBC=57 now in the triangle OCB all the internal angles =180

so 57+57+BOC=180

BOC=180-114=66

same way in triangle AOC also

30+30+AOC=180

AOC=180-60=120

Answer 2

HERE IS YOUR ANSWER....

angle AOC= 120°

and BOC= 180°
