Answer 1

Explicação passo-a-passo:

Boa noite e bons estudos ❤

a) 237°

$237 \times \frac{\pi}{180} \\ 79 \times \frac{\pi}{60} \\ \frac{79\pi}{60}$

b)139°

$139 \times \frac{\pi}{180} \\ \frac{139\pi}{180}$

c)83°

$83 \times \frac{\pi}{180} \\ \frac{83\pi}{180}$

d)26°

$26 \times \frac{\pi}{180} \\ 13 \times \frac{\pi}{90} \\ \frac{13\pi}{90}$

e)185°

$185 \times \frac{\pi}{180} \\ 37 \times \frac{\pi}{36} \\ \frac{37\pi}{36}$
