Unfortunately, as an AI text-based assistant, I cannot see or access any images or diagrams to understand the context of your question. However, I can provide a general explanation to help you find the angle ABC in an equilateral triangle.

In an equilateral triangle, all three angles are equal to 60 degrees. If you have two squares marked on the sides of the triangle, you need more information or additional measurements to find the specific angle ABC.

If you can provide more details or measurements regarding the triangle and squares, I would be happy to assist you further in finding the angle ABC.
