Question

coseno de 30 + seno de 45 igual a

Answer 1

Cosseno de 30° =$\frac{\sqrt{3} }{2}$

Seno de 45° = $\frac{\sqrt{2} }{2}$

$\frac{\sqrt{3} }{2} = 0.866025403...$$\frac{\sqrt{2} }{2} = 0,707106781...$

Se somarmos os valores:

$\frac{\sqrt{3}+\sqrt{2} }{2}$

ou

0,866025403 + 0,707106781 ≈

1,573132184 ...
