Question

Помогите решить!!!!!!!!!

Answer 1

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