# Dot Expansion

**Geometry**Level 3

**\(v = 1,2 \text{ cm/s}\)**) . Let \( \alpha\) be the time, in seconds, that it takes to both dots meet in their expansions on the lines B and B'. Also, let \( \beta\) be the distance, in centimeters, that the dot II runs on the line B' until it meets the dot I on the line B. Consider \( \epsilon = \alpha + \beta\). What is the value of \( \lfloor\epsilon\rfloor\)?

**Notes and Assumptions**:

Use a protractor on a notebook page to create the lines B and B'. Try to do just as the image. Do **not** use trigonometric measures for the given angles (for real). Also, consider that the initial positions, vertical and horizontal, of both dots is 0 centimeters.
