Answer 1

Answer:

answer is=2√3/4...

and good morning

Answer 2

Answer:

cos 60 = $\frac{1}{2}$

cos 30 = $\frac{\sqrt{3} }{2}$

sin 60 = $\frac{\sqrt{3} }{2}$

sin 30 = $\frac{1}{2}$

= $\frac{1}{2}$ x $\frac{\sqrt{3} }{2}$ + $\frac{1}{2}$ x $\frac{\sqrt{3} }{2}$

= $\frac{\sqrt{3} }{4}$ + $\frac{\sqrt{3} }{4}$

= $\frac{2\sqrt{3} }{4}$
