Question

what's the measure of each angle in an equilateral triangle

Answer 1

The answer is 60°

Explaination:

Since all the angles of an equilateral triangle are equal , let each angle be x

Sum of angles in a triangle = 180°

So,

$x + x + x = 180$
$3x = 180$
$x = \frac{180}{3}$

x = 60

Thus,

It can be seen that the sum of angles in a triangle is 60°

Answer 2

60 degree
proof:- Let the angle be x degree
then we know that the equilateral triangle the sides and angle is equal
therefore, x+x+x=180(sum of the triangle is 180 degree)
3x=180
x=180/3
x=60
hence,the measure of each angle is an equilateral triangle is 60 degree.

I hope this will help you
