1. The problem is to find the missing angle in a triangle where two angles are given as 65° and 65°. 2. The sum of the interior angles in any triangle is always 180°. This is a fundamental rule in geometry. 3. To find the missing angle, use the formula: $$\text{Missing angle} = 180^\circ - (\text{Angle 1} + \text{Angle 2})$$ 4. Substitute the given angles: $$\text{Missing angle} = 180^\circ - (65^\circ + 65^\circ)$$ 5. Simplify inside the parentheses: $$\text{Missing angle} = 180^\circ - 130^\circ$$ 6. Calculate the difference: $$\text{Missing angle} = 50^\circ$$ 7. Therefore, the missing angle in the triangle is $50^\circ$. This completes the solution for the first problem.
