Answer:
10 2/5 meters long
Step-by-step explanation:
first turn 20 4/5 into an improper fraction (104/4) then multiply that by 1/2 and you get 104/10 but simplify it to 10 2/5
Hope this helps!
Sin 30=opposite side/hypotenuse =8/x
1/2=8/x so 1•x=2•8; x=16
Sin60= opposite side/hypotenuse=y/16
(Sqrt 3)/2=y/16 so 2•y=16• sqrt 3; y=13.856
I got the answer 10 if not sorry
