    It is easy follow my steps

    make a triangle roughly , then name the angle at left be angle c and angle at right be angle b also angle at top be angle a

    Now draw two line from b/w angle b and c so they meet at a common point o

    ans:

    Given: angle a=60°

    angle b=80°

    To find: angle c and angle BOC

    Solution: angle a+b+c =180°[angle sum property of triangle ]

    60+80+c=180

    c=180-140

    c=40

    therefore angle c =40

    angle boc + angle bco + angle cbo = 180°(Angle sum property…..)

    angle boc + 20 + 40 =180

    angle boc = 180-60

    angle boc = 120°

    I have taken half values in above equation because ob or oc bisect both the angles into 2 equal halves

    HOPE IT HELPS U……PLEASE MARK MEHAS BRAINLIEST…!!

    even the word bisect means dividing an angle into 2 equal halves
