We know that all the angles of an equilateral triangle are equal. So we can take these angles be x.
Now , x+x+x= 180° [Angle sum property]
So,
3x=180°
x= 180°/3
x = 60°
Hence proved...

Thank you but it is no concept of this question..
Means?
it is not correct formation of this question
have u another process solve it??
I don't have any other process of this question...But i know that for this it is the crct process...If there is a question change then their is an other process...If the question is just to prove sum of two angles all angles of a triangle is 180 d then the answer is other. ...

let ABC be an equilateral triangle
We know that in an equilateral triangle, all angles are equal. i.e.
angle A = angle B = angle C-(1)
angle A + B + C = 180° [Angle sum property of a triangle ]
From equation (1)
angle A +A +A =180°
3A= 180°
A=60°
hence angle A=B=C=60°
proved
