1. **State the problem:** We need to find the size of angle ABC to the nearest degree. 2. **Understanding the setup:** The protractor is placed with the flat edge along points B to A, where line BA is at 0 degrees (horizontal to the right). 3. **Reading the angle:** Line BC extends from point B and intersects the protractor's outer scale at approximately 160 degrees. 4. **Formula and rules:** The angle at vertex B between lines BA and BC is measured counterclockwise from BA to BC. Since BA is at 0 degrees, the angle ABC is simply the reading on the protractor where BC crosses. 5. **Conclusion:** The size of angle ABC is approximately $$160^\circ$$. **Final answer:** $$\boxed{160^\circ}$$
