Question

Si sen(x + 60) =7/8, calcula el senx + raiz de 3 cosx

Answer 1

Respuesta:

$\sin(x + 60) = \sin(x) \cos(60) + \sin(60) \cos(x) \\ \frac{7}{8} = \sin(x) \times \frac{1}{2} + \frac{ \sqrt{3} }{2} \cos(x) \\ \frac{7}{8} = \frac{1}{2} ( \sin(x) + \sqrt{3} \cos(x) ) \\ \frac{ \frac{7}{8} }{\frac{1}{2} } = \sin(x) + \sqrt{3} \cos(x) \\ \frac{7}{4} = \sin(x) + \sqrt{3} \cos(x)$
