Переведите из градусной меры в...

Умножаем градусную меру на дробь $\frac{\pi}{180}$ , а затем сокращаем.

430° = $430*\frac{\pi}{180}=\frac{43\pi}{18}$ ;

450° = $450*\frac{\pi}{180}=\frac{5\pi}{2}$ ;

900° = $900*\frac{\pi}{180}=5\pi$ ;

390° = $390*\frac{\pi}{180}=\frac{13\pi}{6}$ ;

33° = $33*\frac{\pi}{180}=\frac{11\pi}{60}$ ;

15° = $15*\frac{\pi}{180}=\frac{\pi}{12}$ ;

10° = $10*\frac{\pi}{180}=\frac{\pi}{18}$ ;

20° = $20*\frac{\pi}{180}=\frac{\pi}{9}$ ;

85° = $85*\frac{\pi}{180}=\frac{17\pi}{36}$ ;

160° = $160*\frac{\pi}{180}=\frac{8\pi}{9}$ ;

200° = $200*\frac{\pi}{180}=\frac{10\pi}{9}$ ;

35° = $35*\frac{\pi}{180}=\frac{7\pi}{36}$ ;

60° = $60*\frac{\pi}{180}=\frac{\pi}{3}$ ;

760° = $760*\frac{\pi}{180}=\frac{38\pi}{9}$ ;

45° = $45*\frac{\pi}{180}=\frac{\pi}{4}$ ;

350° = $350*\frac{\pi}{180}=\frac{35\pi}{18}$ ;

700° = $700*\frac{\pi}{180}=\frac{35\pi}{9}$ .
