Answer:

We already know that,

Sin(x + y) = SinxCosy + CosxSiny

just like that,

Sin30°cos60° + cos30°sin60° = sin90°

sin(30° + 60°) = sin90°

Sin90° = Sin90°

Hence proved☺

Step-by-step explanation:

 \scriptsize{Sin 30° cos 60°+ cos 30° sin 60°}

 \frac{1}{2}  \times  \frac{1}{2}  +  \frac{ \sqrt{ 3} }{2}  \times  \frac{ \sqrt{3} }{2}

 \frac{1}{4}  +  \frac{ \sqrt{9} }{4}

 \frac{1}{4}  +  \frac{3}{4}

 \frac{1 + 3}{4}

 \frac{ \cancel4}{\cancel4}
