    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!

    plz mark me as brainliest!
