Question

I want solution of the question​

Answer 1

Step-by-step explanation:

Answer:

360

Step-by-step explanation:

exterior angle = sum of two opposite interior angles

let say a b c are internal angles

then x = a+b

y = b+c

z = c+a

adding all three

x + y + z = 2*(a+ b +c)

sum of interior angles of s triangle = 180 deg

= 2 * (180)

= 360 deg
