Question

find the measure of angle of equilateral traingle

Answer 1

In equilateral triangle all the sides are of same length.

So we know that total measure of all angles in a triangle is 180°

Taking the measure of angle as x

we solve as

x + x + x = 180

3x = 180

so x = 60°

Hope it helps!

Answer 2

60 degree because all sides are equal
