Question

CALCULE OS VALORES DAS MEDIDAS X e Y?​

Answer 1

Por trigonometria, nós temos:

$a) \: \cos(45) = \frac{x}{16}$

$\frac{ \sqrt{2} }{2} = \frac{x}{16}$

$2x = 16 \sqrt{2}$

$x = \frac{16 \sqrt{2} }{2}$

$x = 8 \sqrt{2}$

------------------------------------------------------------

$b) \: \tan(60) = \frac{y}{20}$

$\sqrt{3} = \frac{y}{20}$

$y = 20 \sqrt{3}$
