Answer:
Sum of all interior angles of a triangle= 180°
Each angle of a triangle= 180°/3= 60°
So, interior angle of x,y,z= 60°
Exterior angle of x= 180°-60°(Linear Pair)
=120°
Exterior angle of y= 180°-60°(Linear Pair)
=120°
Exterior angle of z= 180°-60°(Linear Pair)
=120°
Sum of x+y+z= 120°+120°+120°
= 360°
Hope, it's help you.
