Question

please tell the answer of this


​

Answer 1

The.Sum of exterior angels of a triangle is 360°

x+x+x= 360

3x=360

x= 360/3

x= 120°

y=x ( vertically opposite angles)

y= 120

Answer 2

Answer:

The sum of all exterior angles of a triangle is 360°

ATQ,

x+x+x=360°

3x=360°

x=360/3

x=120°

The measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles.

Until and unless all the angles are equal, the sum of all 3 exterior angles cannot be the same.

⇒All the angles of the triangle are equal to y

The sum of all interior angles of a triangle is 180°

ATQ,

y+y+y=180°

3y=180°

y=180/3

y=60°
