Question

Sin 30 X cos 45°+ Sin 45°x cos 30​

Answer 1

Step-by-step explanation:

$\sin(30) °\times \cos(45)° + \sin(45)° \times \cos(30)°$

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

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

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

Hope it will help you mate.

Answer 2

Answer:

(1 +under root 3/2 under root 2)

Step-by-step explanation:

(sin 30 )( cos 45 ) +( sin 45)( cos 30 )

substituting values

(1/2)(1/under root 2) + (1/under root 2)(under root 3/2)

= (1/2 under root 2) + (under root 3/2 under root 2)

=  (1 +under root 3/2 under root 2)
