Question

Triangle b top corner lower right corner lower left corner

Answer 1

Let's begin by listing out the given information:

Triangle ABC is an equilateral triangle (it has its three sides & angles to be congruent)

`m\angle C=60^(\circ)`

The three sides of the triangle have a single tick which indicates their congruence. This implies that:

`m\angle C=m\angle A=m\angle B=60^(\circ)`

Therefore, the answer is 60 degrees
