Question

Плачу много баллов!!!

Answer 1

Ответ:

1) $\sin(180^{\circ} - \alpha )=\dfrac{1}{3}$

2) $\cos(180^{\circ} - \alpha )= -0,7$

3) $\cos(180^{\circ} - \alpha ) = \dfrac{4}{9}$

4) $tg(180^{\circ} - \alpha ) = 5$

Объяснение:

За формулами зведення:

$\sin(180^{\circ} - \alpha ) = \sin \alpha$

$\cos(180^{\circ} - \alpha ) = -\cos \alpha$

$tg(180^{\circ} - \alpha ) = - tg\ \alpha$

1) $\sin(180^{\circ} - \alpha ) = \sin \alpha = \dfrac{1}{3}$

2) $\cos(180^{\circ} - \alpha ) = -\cos \alpha = -0,7$

3) $\cos(180^{\circ} - \alpha ) = -\cos \alpha = - (-\dfrac{4}{9} )=\dfrac{4}{9}$

4) $tg(180^{\circ} - \alpha ) = - tg\ \alpha = -(-5) = 5$
