Question

Алгебра...............

Answer 1

Ответ:

$\frac{\pi}{6}rad; \quad \frac{35\pi}{36}rad; \quad 84^{\circ};$

Объяснение:

$30^{\circ}=(30 \cdot \frac{\pi}{180})rad=\frac{\pi}{6}rad;$

$175^{\circ}=(175 \cdot \frac{\pi}{180})rad=\frac{35\pi}{36}rad;$

$\frac{7\pi}{15}rad=(\frac{7\pi}{15} \cdot \frac{180}{\pi})^{\circ}=84^{\circ};$
