Question

plz..answer if u know..​

Answer 1

Answer:$20 \sqrt{3}$remember a centroid divides a median in the ratio 2 is to 1, so OA will be equal to 20 metre and OE is will be equal to 10 metre and you can find that OA and OE together forms a median and their ratio is also 2 is to 1 . when you find OE is equal to 10 metre using hypotenuse theorem you can find the value of EC , so it would be the half of the length of string, so you have multiple it by 2 to get the length of the string.if you hope it is correct then mark me as brainiest
