Question

Resolver: A = sen53º.cos60º + sen37º.sen30º

Answer 1

Respuesta:

Explicación paso a paso:

          $0.7$

$A = Sen 53 *Cos 60 + Sen 37 * Sen 30$

$Cos 60 = \frac{1}{2}$         ;     $Sen 30 = \frac{1}{2}$

$A = (Sen 53)*( \frac{1}{2} ) + (Sen 37 )*(\frac{1}{2} ) = \frac{1}{2} (Sen 53 + Sen 37)$

$A = 0.5 ( 0.7986 + 0.6018 ) = 0.5 ( 1.4 )$

$A = 0.7$
