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.
