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...
