Let me know if you'd like further explanations or clarification!

1. What is the sum of angles in any triangle?
2. What is the relationship between the angles of a triangle and the concept of supplementary angles?
3. How do we calculate missing angles in any geometric shape?
4. Can the method used here be applied to polygons with more sides?
5. Why is it important to understand the sum of interior angles in geometry?

Tip: Always remember that the sum of interior angles in any triangle is always 180°.
