Answer:
60°
Step-by-step explanation:
The measure of each angle of an equilateral triangle is 60°.
An equilateral triangle is a kind of triangle where all angles are equal to each other.
The sum of angles of a triangle is equal to 180
A triangle has 3 sides
Calculating the measure of each angle,
a + a + a = 180°
3a = 180°
a = 180 / 3
Therefore a = 60°
