Question

Transformati in grade radianii: pu supra 8; 2 pi supra 5, 3 pi supra 5; pi supra 12

Answer 1

pe pi îl înlocuiești cu 180 și calculezi

$\frac{\pi}{8}rad = \frac{180}{8} = 22. 5grade \\ \\ \frac{2\pi}{5}rad \: = \frac{2 \times 180}{5} = 72grade \\ \\ \frac{3\pi}{5} rad= \frac{3 \times 180}{5} = 108grade \\ \\ \frac{\pi}{12}rad = \frac{180}{12} = 15grade$

Answer 2

$\it \pi=180^o\\ \\ \dfrac{\pi}{8}=\dfrac{180^o}{8}=\dfrac{45^o}{2}=\dfrac{44^o60'}{2}=22^o30'\\ \\ \\ \dfrac{\pi}{5}=\dfrac{180^o}{5}=36^o$
