Question

please answer the question ​

Answer 1

Answer:

180-z+ 180-y + 180-x= 180 (angle sum property)

540-180= x+y+z

=> x+y+z= 360°

please thank if it helps you

Answer 2

Answer:

According angle sum property of triangle = All outer angles of equilateral triangle is equal in measure and their sum is 360 degree

so let us assume all angles are x

so = 3x = 360 degree

x = 360/3 = 120 degree

So , Angle x - 120 degree

Angle y - 120 degree

Angle z - 120 degree
