Question

cos 60°×cos 30°+sin 60°×sin 30°​

Answer 1

Step-by-step explanation:

1/2 × √3/2 +√3/2 × 1/2=√3/2

Answer 2

$= \cos(60) \times \cos(30) + \sin(60) \times \sin(30) \\ = \frac{1}{2} \times \frac{ \sqrt{3} }{2} + \frac{ \sqrt{3} }{2} \times \frac{1}{2} \\ = \frac{2( \sqrt{3} )}{2} \\ = \sqrt{3} +$

hope it helps you.
