Question

ХЕЛП ОЧЕНЬ СРОЧНО!!!!!!!!!

Answer 1

Ответ:

$500^\circ =360^\circ +140^\circ \ \ -\ \ 2\ chetvert\\\\-1290^\circ =-3\cdot 360^\circ -210^\circ \ \ -\ \ 2\ chetvert\\\\\dfrac{19\pi }{3}=3\cdot 2\pi +\dfrac{\pi }{3}\ \ -\ \ 1\ chetvert\\\\-\dfrac{100\pi }{7}=-7\cdot 2\pi -\dfrac{2\pi }{7}\ \ -\ \ 4\ chetvert\ \ \ \Big(\dfrac{2\pi}{7}\approx 51,4^\circ \Big)\\\\2,5\ rad\approx 2,5\cdot 57,3^\circ =143,25^\circ \ \ -\ 2\ chetvert\\\\-7\ rad\approx -7\cdot 57,3^\circ =-401,1^\circ =-360^\circ-41,1^\circ \ \ -\ \ 4\ chetvert$
