URGENTE PLEASEEEE.

SIMPLIFIQUE A EXPRESSÃO:

A= 1+SEN300°
------------------------------
Tan540°+cos(-120°)

Answer 1

$\frac{1 + \sin(300) }{ \tan(540) + \cos( - 120) } \\ \\ \frac{1 - \frac{ \sqrt{3} }{2} }{0 - \frac{1}{2} } \\ \\ \frac{1 - \frac{ \sqrt{3} }{2} }{ - \frac{1}{2} } \\ \frac{2(1 - \frac{ \sqrt{3} }{2}) }{ - 1} \\ =\sqrt{3} - 2$
