Hi Mate!!!!!
Sin ( A + B ) = Sin ( A ) + Sin ( B ) this identity holds some times good ....like for angles A = 0°
and B = 90° . but this is not sufficient to get the generalized result of Sin ( A + B ) ....
In nutshell Sin ( A + B ) = Sin ( A ) + Sin ( B ) is absolutely wrong....
Sin ( A + B ) = Sin ( A ) Cos ( B ) + Cos ( A ) Sin ( B )
Have a nice time.

No,
Because if we take sinA as 30 and sinB as 60
sin (60+30)=sin 30 +sin 60
sin 90=1/√2+ √3/2
1=1.75
1≠1.75
so sin(a+b) is not equal to sina + sinb
