Answer 1

Hola (｡•̀ᴗ-)✧

Respuesta:

$\boxed{ \texttt{sen} (a) = \frac{\sqrt{2} }{ 2} }$

Explicación paso a paso:

sen(a) , Si cos²(a)=1/2

---------------------------------------

sen²(a)+cos²(a) = 1

--------------------------------------

sen²(a) + 1/2 = 1

sen²(a) = 1 - 1/2

sen²(a) = 1/2

sen(a) = 1/√2

sen(a) = √2 / 2
