Question

De acordo com as colunas acima, a ordem correta é:

a) 1-C, 2-A, 3-D, 4-B, 5-E
b) 1-A, 2-B, 3-C, 4-D, 5-E
c) 1-B, 2-C, 3-D, 4-E, 5-A
d) 1-C, 2-A, 3-D, 4-E, 5-B

Answer 1

Basta analisar a tabela:

$sen \: (60°) = \frac{ \sqrt{3} }{2}$

$sen \: (30°) = \frac{1}{2}$

$cos(45°) = \frac{ \sqrt{2} }{2}$

$tg(60°) = \sqrt{3}$

$cos(2\pi) = 1$

Correta (A)
