Answer:Step-by-step explanation:heya mate!

have a good day!

if AB = AC [ then angle ABC = angle ACB]

let angle ABC and angle ACB be x

since, the circumcentre acts as an angle bisector

angle ABO = angle ACO = x/2

as ABO and ACO is half of ABC and ACB…..

so by angle-sum property,

ABO + ACO + BOC = 180°

2(x/2) + 100 = 180°

x = 180-100

(ABC)x = 80°

ABO = x/2 = 80°/2 = 40°

hope it helps!
