Respuesta:

Fácil mi coronita plis :D

Explicación paso a paso:

$M=\frac{Cos(30-x)+Cos(30+x)}{Sen(30-x)+Sen(30+x)} \\\\M=\frac{[Cos(30).cos(x)+Sen(30).Sen(x)]+[Cos(30).Cos(x)-Sen(30).Sen(x)]}{[Sen(30)cos(x)-Sen(x)Cos(30)]+[Sen(30).Cos(x)+Sen(x).Cos(30)]} \\\\\\M=\frac{2.Cos(30).Cos(x)}{2.Sen(30).Cos(x)} \\\\M=Ctg(30)\\\\M=\sqrt{3}$
