Question

reducir, es trigonometría​

Answer 1

$\boxed {\bold{W =2 }}$

Procedimiento:

Reducir

$\boxed {\bold{W =\frac{sen(20\°)}{cos(70\°) } +\frac{tan(50\°)}{ctg(40\°)} }}$

$\boxed {\bold{W =\frac{0,34202014}{0,34202014 } +\frac{1,19175359}{1,19175359} }}$

$\boxed {\bold{W =\frac{1}{1 } +\frac{1}{1} }}$

Simplificando - Anulando factor común-

$\boxed {\bold{W =1 + 1 }}$

$\boxed {\bold{W =2 }}$
