Question

cos 60 × cos 30 + sin 60 ×sin 30

Algebra question ​

Answer 1

$\cos(60) \times \cos(30) + \sin(60) \times \sin(30) \\ \frac{1}{2} \times \frac{ \sqrt{3} }{2} + \frac{ \sqrt{3} }{2} \times \frac{1}{2} \\ \frac{ \sqrt{3} }{4} + \frac{ \sqrt{3} }{4} \\ \frac{2 \sqrt{3} }{4}$

HAVE A NICE DAY!!!
