Question

Помогите решить!!!!!!!!!

Answer 1

$\pi = 180° \\ 1) \frac{\pi}{10} = \frac{180}{10} = 18° \\ 2) \frac{\pi}{8} = \frac{180}{8} = 22.5° \\ 3) \frac{5\pi}{9} = 100°$
$4) \frac{\pi}{2} = 90° \\ 5) \frac{7\pi}{6} = 210° \\ 6)\pi = 180°$
$7) \frac{11\pi}{9} = 220° \\ 8) \frac{3\pi}{4} = 135° \\ 9)0.3\pi = 0.3 \times 180° = 54°$
$10) \frac{21}{8} \pi = 472.5° \\ 11) - \frac{\pi}{4} = - 45° \\ 12) - \frac{100\pi}{3} = - 6000°$
$13) \frac{5\pi}{2} = 450° \\ 14) - \frac{7\pi}{4} = 315° \\ 15) \frac{21\pi}{2} = 1890°$
$16) - 3\pi = - 540° \\ 17) \frac{11\pi}{4} = 495° \\ 18) \frac{39\pi}{18} = 390°$
