Question

In fig AOC and BOC form linear pair if a-b=80find the value of a and b​

Answer 1

Step-by-step explanation:

$a + b = 180 \\ a - b = 80 \\ 2a = 260 \\ a = 130 \\ b = 50$

Answer 2

Answer:

To find : values of a and b

a−b=80

∘

...(1)

a+b=180 [Linear pair]

Add both equations

2a=260

∘

a=130

∘

Put a=130

∘

in equation (1)

b=50
