Respuesta:

sen(80)

Explicación paso a paso:

sen (1520)

sen [((72+4)/9)*180]

sen [((72/9)  +  (4/9))*180]

sen [(72/9)*180  +  (4/9)*180]

sen [(360*4)  + (4/9)180]

sen [360*4  + (4/9)180]

sen [ (4/9)180+(360*4)]

Usamos propiedad: sen (x+360*k ) = sen(x)

sen [(4/9)*180]

sen [720/9]

sen(80)
