Answer:

x= 120°

Step-by-step explanation:

By first method-

exterior angle= sum of two opposite interior angle

x= 60°+60°

x = 120°

By second method-

sum of interior angles of triangle is= 180°

Let one interior angle be y

then

60°+60° +y = 180°

120°+y= 180°

y= 180°-120°

y= 60°

Now

x+y = 180°[ linear pair]

x+ 60°=180°[y=60°]

x= 180°-60°

x=120°
