si: secX=√7
Calcular: E=Tan²x+√42SenX

Answer 1

Respuesta:

             $12$

Explicación paso a paso:

$Sec (x ) = \frac{\sqrt{7} }{1}$           ;       $Sen (x )=\frac{\sqrt{6} }{\sqrt{7} }$       ;      $tan(x)= \frac{\sqrt{6} }{1}$

$E = Tan^{2} (x ) + \sqrt{42} Sen(x )$

$E = ( \sqrt{6} )^{2} + \sqrt{42} (\frac{\sqrt{6} }{\sqrt{7} } ) = 6 + \sqrt{\frac{252}{7} }= 6 + \sqrt{36} =6 + 6$

$E = 12$
