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
