a-b=30
a+b=180 (by linear equation)
a-b=30
a+b=180
2a=210
a=105

a-b=30
105-b=30
b=75

Hope u understand pls reply

Answer:

a=105       b=75

Explanation given below.

Step-by-step explanation:

Given: a-b=30, AB is a straight line

To find: value of a and b

Answer:

a-b=30 [Given].....(i)

a+b=180 [Linear Pair]........(ii)

From equation (i) and (ii)

a+a-b+b=180+30

2a=210

a=210/2

a=105

a+b=180 [Linear Pair]

Now we have the value of a as 105

So,

105+b=180

b=180-105

b=75

I hope it helps...
