Answer:

Mark as brainlist
Step-by-step explanation:
X + y = 120(being alternate angle)
or,X=120-y
then
2x-y=120
or,2(120-y) - y= 120
240-2y-y=120
y=240-120
y= 120
again,
X=120-y
= 120-120
=0
hence,
X= 0
y= 120
Answer:
x=0 , y = 120
Step-by-step explanation:
x+y = 120°
x = 120 - y ---------(1)
2x-y= 120°----------(2)
substitute x = 120-y in (2)
»» 2(120-y)-y = 120
240-2y-y =120
240-y = 120
y = 240 -120
= 120
substitute y = 120 in (1)
x= 120-120
= 0
