We know that on straight angle = 180°
so, x+20° +2x-20°+ 60° = 180°
3x =120°
x= 40°
angle AOC= X+20°= 60•
angleCOD= 2X -20° = 60°
so, x+20° +2x-20°+ 60° = 180°
3x =120°
x= 40°
angle AOC= X+20°= 60•
angleCOD= 2X -20° = 60°

hey here is ur answer
these three angles lie on a straight line which means that there sum will be 180 degree
x+20+2x-20+60=180
3x+60=180
3x=180-60
3x=120
x=120/3
x=40degree
now according to the question
1 angle=x+20=40+20=60degree
2 angle=2*40 -20=60degree
3angle= 60 degree
hope it helps nd plzzz mark me as brainlist
