Answer 1

Explicação passo-a-passo:

Boa tarde e bons estudos ❤

a) 35°

$35 \times \frac{\pi}{180} \\ 7 \times \frac{\pi}{36} \\ \frac{7\pi}{36}$

b)130°

c) 90°

$90 \times \frac{\pi}{180} \\ \frac{\pi}{2}$

d) 45°

$45 \times \frac{\pi}{180} \\ \frac{\pi}{4}$

e) 180°

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

f) 60°

$60 \times \frac{\pi}{180} \\ \frac{\pi}{3}$

g) 360°

$360 \times \frac{\pi}{180} \\ 2\pi$

h) 270°

$270 \times \frac{\pi}{180} \\ \\ 3 \times \frac{\pi}{2} \\ \frac{3\pi}{2}$
