The regular heptagon is inscribed in a circle. Calculate the magnitudes of the interior angles of the chordal quadrilateral \(ACEG\). (See the picture.)
\( \alpha=4\cdot\frac{360^{\circ}}{14}\); \( \beta=3\cdot\frac{360^{\circ}}{14}\); \( \gamma=3\cdot\frac{360^{\circ}}{14}\); \( \delta=4\cdot\frac{360^{\circ}}{14}\)
\( \alpha=4\cdot\frac{360^{\circ}}{7}\); \( \beta=3\cdot\frac{360^{\circ}}{7}\); \( \gamma=3\cdot\frac{360^{\circ}}{7}\); \( \delta=4\cdot\frac{360^{\circ}}{7}\)
\( \alpha=4\cdot\frac{180^{\circ}}{14}\); \( \beta=3\cdot\frac{180^{\circ}}{14}\); \( \gamma=3\cdot\frac{180^{\circ}}{14}\); \( \delta=4\cdot\frac{180^{\circ}}{14}\)
\( \alpha=4\cdot\frac{360^{\circ}}{14}\); \( \beta=4\cdot\frac{360^{\circ}}{14}\); \( \gamma=3\cdot\frac{360^{\circ}}{14}\); \( \delta=3\cdot\frac{360^{\circ}}{14}\)
