Упр.1.1 ГДЗ Мордкович Семенов 10 класс (Алгебра)

а) $$\overset{\frown}{AB}=\frac{\pi}{6};$$

$$\overset{\frown}{AN}=\frac{2\pi}{6}=\frac{\pi}{3};$$

$$\overset{\frown}{BK}=\frac{\pi}{4};$$

$$\overset{\frown}{MN}=\frac{3\pi}{4}-\frac{\pi}{6}=\frac{9\pi-2\pi}{12}=\frac{7\pi}{12};$$

$$\overset{\frown}{CN}=\pi-\frac{\pi}{3}=\frac{2\pi}{3}.$$

б) $$\overset{\frown}{BM}=\frac{\pi}{6};$$

$$\overset{\frown}{AN}=\pi-\frac{\pi}{6}=\frac{5\pi}{6};$$

$$\overset{\frown}{AK}=\frac{5\pi}{6}-\left(\frac{\pi}{2}+\frac{\pi}{6}\right)=\frac{5\pi}{6}-\frac{2\pi}{3}=\frac{\pi}{6};$$

$$\overset{\frown}{BK}=\frac{\pi}{2}+\frac{\pi}{4}=\frac{3\pi}{4};$$

$$\overset{\frown}{MN}=\pi-\frac{\pi}{6}=\frac{5\pi}{6};$$

$$\overset{\frown}{CN}=\pi-\frac{5\pi}{6}=\frac{\pi}{6}.$$
