Question

find the value of Cos 45 degree Sin 30 degree + Cos 30 degree Sin 45 degree​

Answer 1

Step-by-step explanation:

value of

sin45°.sin30°+cos30°.sin45°

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

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

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