a+b= 180 ( linear pair) -1
a-b = 80 ( given) -2
add equation 1 and 2
after adding we get ...
2a = 260
a= 260÷2
a= 130
130+ b= 180
b = 180-130
b = 50
therefore
a= 130
b= 50
a-b = 80 ( given) -2
add equation 1 and 2
after adding we get ...
2a = 260
a= 260÷2
a= 130
130+ b= 180
b = 180-130
b = 50
therefore
a= 130
b= 50
