we know that sum of
linear pair is 180
-----------------------------
let angle. are x and y
given that ...
x + y = 180 -----eq1
x - y = 80 -----eq2
then ....
according to the question
now.....
add both eqns
then we get
2x = 260
x = 130
so....
y = 50
hence angles are
50 and 130
it is answer

Answer 2

Step-by-step explanation:

x+y=180 equ1

x-y=80 equ2

atq

adding equa1and2

2x=260

1x=130.

y=50
