1. The problem asks to find the values of angles A, B, C, and D in the given geometric figures. 2. Since the user did not specify which figure or provide specific angle relationships, we will assume a common approach: the sum of angles in polygons and linear pairs. 3. For a quadrilateral (4-sided polygon), the sum of interior angles is given by the formula: $$\text{Sum of interior angles} = (n-2) \times 180^\circ$$ where $n=4$ for a quadrilateral, so: $$\text{Sum} = (4-2) \times 180^\circ = 2 \times 180^\circ = 360^\circ$$ 4. If angles A, B, C, and D are the interior angles of a quadrilateral, then: $$A + B + C + D = 360^\circ$$ 5. Without additional information about the values or relationships between these angles, we cannot find unique values for A, B, C, and D. 6. If you provide specific angle measures or relationships (e.g., A = 60°, B = 90°, or A + B = C), we can solve for the unknowns. 7. Please provide more details or specify which figure and angles you want to solve for. Final answer: Cannot determine unique values for A, B, C, and D without more information.
