Question

Calcule o valor de x em cada caso

Answer 1

a)

$\sin(18) = \frac{x}{10} \\ 0,30 = \frac{x}{10} \\ x = 10.0,30 \\ x = 3$

b)

$\tan(36) = \frac{8}{x} \\ 0,72 = \frac{8}{x} \\ 0,72x = 8 \\ x = \frac{8}{0,72} \\ x = 11,11$

c)

$\cos(70) = \frac{x}{18} \\ 0,34 = \frac{x}{18} \\ x = 18.0,34 \\ x =6,12$

d)

$\tan(26) = \frac{x}{16} \\ 0,48 = \frac{x}{16} \\ x = 16.0,48 \\ x = 7,68$
