Triangle Side Analysis: Determining if ABC is an Equilateral Triangle

To determine whether the triangle is equilateral, follow these steps:

• Simplify each side of the triangle, labelled as "X+X", to express it as $2X$.
• Check the lengths of the sides:
• The first side is $2X$.
• The second side is also $2X$.
• The third side is again $2X$.
• Since all three sides have the same length of $2X$, the triangle is equilateral.

Therefore, the conclusion is that the triangle is indeed equilateral.

The solution corresponds to choice 2.
