Question

Sin23°.cos22°+cos23°.sin22°=1/2

Answer 1

Here is your right answer

Answer 2

$\huge\mathfrak{Answer:-}$

$\large\tt{We\:know,}$

$\small\tt{Sin(A+B)=SinA.CosB+CosA.SinB}$

$\therefore$$\small\tt{In\:Sin23.Cos22+Cos23.Sin22}$

$\small\bf{A=23,B=22}$

$\small\tt{Sin(23+22)=Sin45}$

$\small\tt{Sin45=}$$\small\frac{1}{2}$

$\therefore$$\small\bf{LHS=RHS}$
