Question

In figure angle AOC and angle BOC form a linear pair .If a-b=20 find the value of a,b and make figure​

Answer 1

Answer:

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°
