Question

алгебра нужна помощь номер 3 (в,г)номер 4 все.​

Answer 1

$4. \\ - 405 {}^{0} = - \frac{405{}^{0} \times \pi}{180 {}^{0} } = - \frac{9\pi}{4} \\ - 22.5 {}^{0} = - \frac{22.5 {}^{0} \times \pi}{180 {}^{0} } = - \frac{22.5\pi}{180 {}^{0} } .$

4.

$\frac{3\pi}{4} = \frac{3 \times 180 {}^{0} }{4} = 135 {}^{0}$

$2.5\pi = 2.5 \times 180 {}^{0} = 450 {}^{0}$

$0.3\pi = 0.3 \times 180 {}^{0} = 54 {}^{0}$

$\frac{11\pi}{3} = \frac{11 \times 180 {}^{0} }{3} = 660 {}^{0}$
