Question

considere as afirmações i cos 95=-cos 85

Answer 1

Resposta:

F) 0

Explicação passo a passo:

I) $\cos \left(95^{\circ \:}\right)=-\cos \left(85^{\circ \:}\right)$

$Falso$

II) $\cos \left(225^{\circ \:}\right)=\cos \left(85^{\circ \:}\right)$

$-\frac{\sqrt{2}}{2}=\cos \left(85^{\circ \:}\right)$

$Falso$

III) $\tan \left(275^{\circ }\right)=-\tan \left(85^{\circ }\right)$

$Falso$

IV) $\sin \left(355^{\circ \:}\right)=-\sin \left(85^{\circ \:}\right)$

$Falso$

V) $\cot \left(175^{\circ \:}\right)=-\cot \left(85^{\circ \:}\right)$

$Falso$
