Step-by-step explanation:
Angle AOC =100° & BOC =80°
Step-by-step explanation:
Given,
Angle AOC & BOC form linear pair.
Therefore,
Angle AOC + Angle BOC = 180°
Again,
Angle a - Angle b = 20
Now,
Angle a can also be written as,
a= 20 + b
Therefore,
20+b+b= 180°(Since Angle AOC & Angle BOC form linear pair)
2b = 160°
b = 80°
therefore,
a = 20+b
a = 100
