Упр.408 ГДЗ Алимов 10-11 класс (Алгебра)

1) пи/6; 2)пи/9 3)3пи/4; 4)2; 5)3; 6)0,36.

1. $$\frac{\pi}{6}=\frac{\pi}{6}\cdot\frac{180^\circ}{\pi}=30^\circ$$
2. $$\frac{\pi}{9}=\frac{\pi}{9}\cdot\frac{180^\circ}{\pi}=20^\circ$$
3. $$\frac{3\pi}{4}=\frac{3\pi}{4}\cdot\frac{180^\circ}{\pi}=135^\circ$$
4. $$2=2\cdot\frac{180^\circ}{\pi}=\frac{360^\circ}{\pi}\approx 114{,}6^\circ$$
5. $$3=3\cdot\frac{180^\circ}{\pi}=\frac{540^\circ}{\pi}\approx 171{,}9^\circ$$
6. $$0{,}36=0{,}36\cdot\frac{180^\circ}{\pi}=\frac{64{,}8^\circ}{\pi}\approx 20{,}6^\circ$$
