Answer:

x = 3

Explanation:

Since the 3 angles in the triangle are equal, then the triangle is equilateral.

Thus the 3 sides are congruent.

Equate any 2 of the sides and solve for x, that is

12x - 13 = 7x + 2 ( subtract 7x from both sides )

5x - 13 = 2 ( add 13 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3
