Answer:
This is an equilateral triangle, meaning that all sides and all angles are equal, as shown through the three equal side lengths, so all you have to do is find what makes all three angles the same number!
A triangle has 180 degrees, and this one has 3 equal angles because it has 3 equal sides, so 180/3 is 60 degrees!
So C. 60 degrees is your answer!!
Hope this helps!
