60 because all of the side are equal so it would be 180 divided by 3.

Answer:

60 degrees

Explanation:

As shown, this is a equilateral triangle which has the same angle measures.

According to the Triangle Sum Theorem, the sum of all three angles in a triangle is 180 degrees.

Thus,

180 (The sum of all angles in a triangle) /3 (The amount of angles in a triangle) = 60 degrees.
