Question

If x,y and z are exterior angles of triangle ABC, then find th value of x+y+z.

Answer 1

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

Answer 2

Answer:

Step-by-step explanation: if the triangle is isosceles or right angle then x+y+z = 360

if triangle is equilateral the x+y+z = 360

if triangle is scalene then x+y+z = 340
