1. **State the problem:** We have a triangle with two known angles, 82° and 36°, and we need to find the unknown angle $y$. 2. **Formula used:** The sum of the interior angles of any triangle is always 180°. This means: $$y + 82 + 36 = 180$$ 3. **Calculate $y$:** $$y = 180 - 82 - 36$$ $$y = 180 - 118$$ $$y = 62$$ 4. **Conclusion:** The value of the unknown angle $y$ is 62°. This works because the angles inside a triangle always add up to 180°, so subtracting the known angles from 180° gives the missing angle.
