Question

como resuelvo esto y de que formas?
-✓2-2sen(x)=0

Answer 1

${ \sqrt{2} -2sen(x)=0}\\\\{2sen(x)= \sqrt{2} }\\\\{sen(x)= \frac{\sqrt{2}}{2} }\\\\{x=sen^{-1} \left( \frac{\sqrt{2}}{2} \right)}\\\\{\boxed{x=45^{\circ}}}\\\\{\text{salu2.!! :)}$

Answer 2

-✓2-2sen(x)=0
-√2=2senx
-√2
 ---- = senx
   2

donde se deduce que x = 135°  o     x=3π/4
