AS AO= OB

SO IT BECOMES ISOSCELES

therefore OAB = OBA

OAB + OBA + AOB = 180

2 OBA + 70 = 180

OBA = 55

AOC = 180- 70 = 110

AS AOC is isosceles

2 OAC+ 110 = 180
OAC = 35

Answer:

Step-by-step explanation:

AS AO= OB

SO IT BECOMES ISOSCELES

therefore OAB = OBA

OAB + OBA + AOB = 180

2 OBA + 70 = 180

OBA = 55

AOC = 180- 70 = 110

AS AOC is isosceles

2 OAC+ 110 = 180

OAC = 35
