Question

sendo cosx=√3/2, com o < x<90 determine

Answer 1

Olá!


$\boxed{\maths{cos \: x = \frac{\sqrt{3}}{2}} }$, $x \in 0^o < x < 90^o$

$cos \: x = cos \: \frac{\pi}{6} \\ \Leftrightarrow x = \frac{\pi}{6}$

$\pi = 180^o \\ \Leftrightarrow x = \frac{180^o}{6}$
$\Leftrightarrow \boxed{\maths{x = 30^o} }$
