Question

sinxsin(x+30)+cosxsim(x+120)=​

Answer 1

Refer to the above attachment

Answer 2

Answer:

Sinx (sinxcos30 + cosxsin30) + cosx (sinxcos120 + cosx+sin120)

sinx (sinx$\frac{\sqrt{3} }{2}$ + cosx $\frac{1}{2}$) + cosx (-sinx$\frac{1}{2}$+ cosx $\frac{\sqrt{3} }{2}$)

=  (sinx$\frac{\sqrt{3} }{2}$ + cosx $\frac{1}{2}$) (sinx - cosx)
