Answer 2

OA=OB=OC=radius

In △OBC

Since OB=OC

∠OBC=∠OCB

∠BOC=155

∠OBC+∠OCB+∠BOC=180

2∠OCB=180−155

∠OCB=12.5

Similarly in △OAC

2∠OCA=180−55

∠OCA=62.5

2∠OCB=180−155

∠OCB=12.5

SCB = 2∠OCB=180−155

∠OCB=12.5

OCB + 2∠OCB=180−155

∠OCB=12.5

∘

OCA=12.5+62.5=75

∘

hope this is right or wrong I don't know because iam nill in maths once chek it
