aluate the following:
i) sin 60° cos 30° + sin 30° cos 60°​

Answer 1

Answer:

1

Step-by-step explanation:

GIVEN:-

$sin 60° cos 30° + sin 30° cos 60°$

SOLUTION:-

But we know that,

$</em></strong><strong><em>\</em></strong><strong><em>bold</em></strong><strong><em>{</em></strong><strong><em>\</em></strong><strong><em>boxed</em></strong><strong><em>{</em></strong><strong><em>\sin(a)\cos(b)+\sin(b)\cos(a)=\sin(a + b)</em></strong><strong><em>}</em></strong><strong><em>}</em></strong><strong><em>$

since its in this form ,

$= \sin(60 + 30)$

$= \sin(90)$

$= 1$
