Question

.evalua the following
(I) sin 60 ° coa 30°+sin 30°cos 60°​

Answer 1

Given:

sin 60 ° cos 30°+sin 30°cos 60°. (correct Question)

To Find:

Its simified value.

Answer:

=sin 60 ° cos 30°+sin 30°cos 60°.

=√3/2 ×√3/2 +1/2×1/2.

=3/4+1/4.

=4/4.

=1

Answer 2

Step-by-step explanation:

$\green{question::}$

${sin60°cos30°+sin30°cos60°}$

$you \: can \: either \: use \: formula \\ or \: replace \: values \: over \: here$

$\sin(x) \cos(y) + \cos(x) \sin(y) = \\ \sin(x + y)$

$thus \\ \sin(60) \cos(30) + \sin(30) \cos(60) \\ = \sin(60 + 30)$

$\sin(90)$

$= 1$

thus 1 is your answer....
