Answer 2

Answer:

sin30° cos45° + cos30° sin45° =

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

we know

sin45 ° = cos45° = 1/√2

sin30° = ½. and cos30° = √3/2

so, putting these values

we get

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