pls make it fast

Answer 1

$\cos(x) = base \div hyp$
Therefore,
Let L be the length of rope be L
cos 30°=10/L
=>L=20/3^1/2

Answer 2

let QR=10
PR =length of rope
angle PRQ=30°
so
cos 30°=QR/PR
√3/2=10/PR
PR=20/√3
PR=11.54m



Hope you got the explanation because explanation is more important than answer .....
