Перевод радианной меры углов в градусную

1. A) $$rac{7pi}{4} = \frac{7 \cdot 180^{\circ}}{4} = 7 \cdot 45^{\circ} = 315^{\circ}$$
2. Б) $$rac{5pi}{6} = \frac{5 \cdot 180^{\circ}}{6} = 5 \cdot 30^{\circ} = 150^{\circ}$$
3. В) $$rac{11pi}{4} = \frac{11 \cdot 180^{\circ}}{4} = 11 \cdot 45^{\circ} = 495^{\circ}$$
4. Г) $$rac{13pi}{3} = \frac{13 \cdot 180^{\circ}}{3} = 13 \cdot 60^{\circ} = 780^{\circ}$$
5. Д) $$1,5 \pi = 1,5 \cdot 180^{\circ} = 270^{\circ}$$
6. E) $$3 = \frac{3 \cdot 180^{\circ}}{\pi} = \frac{540^{\circ}}{\pi} \approx 171.89^{\circ}$$
