Ответ:
Переводим градусы в радианы по формуле: \(\alpha^\circ=\alpha\cdot\frac{\pi}{180}\).
- 1.1. \(10^\circ=\frac{\pi}{18}\); \(135^\circ=\frac{3\pi}{4}\); \(-60^\circ=-\frac{\pi}{3}\).
- 1.2. \(18^\circ=\frac{\pi}{10}\); \(150^\circ=\frac{5\pi}{6}\); \(-90^\circ=-\frac{\pi}{2}\).
- 1.3. \(30^\circ=\frac{\pi}{6}\); \(144^\circ=\frac{4\pi}{5}\); \(-130^\circ=-\frac{13\pi}{18}\).
- 1.15. \(45^\circ=\frac{\pi}{4}\); \(160^\circ=\frac{8\pi}{9}\); \(-75^\circ=-\frac{5\pi}{12}\).
- 1.16. \(216^\circ=\frac{6\pi}{5}\); \(15^\circ=\frac{\pi}{12}\); \(-60^\circ=-\frac{\pi}{3}\).
- 1.17. \(130^\circ=\frac{13\pi}{18}\); \(72^\circ=\frac{2\pi}{5}\); \(-180^\circ=-\pi\).
