Answer:


Step-by-step explanation:

Use the fact that sin 30 =0.5 and cos 30 = sqrt 3/2

we have answers as

8. u=16 and v = [tex]8\sqrt{3}[/tex]

9) y=5 and x=[tex]5\sqrt{3}[/tex]

10) tan 30 =[tex]\frac{1}{\sqrt{3} }[/tex]

So y=[tex]4\sqrt{3}[/tex]

x=[tex]8\sqrt{3}[/tex]


11) a=22 and b=11

12) b=1.5 and a=[tex]1.5\sqrt{3}[/tex]

13) y=[tex]20\sqrt{3}[/tex]

and x=10
