Question

if the problem was 1^2+9^2=c^2 then the answer would be radical 82, right?

Answer 1

1+81=c^2
82=c^2
are you finding the side of a right triangle? or you finding some kind of length, because it would also be -sqrt(82)

Answer 2

yes. although radical does not always mean square root.

Answer 3

yes dhatraditya is right

Answer 4

but you have two answers unless you are looking for a measurement

Answer 5

well, i'm finding the length of the unknown side of the right triangle, which i guess is c

Answer 6

ok so it is sqrt(82) gj

Answer 7

then it will be the positive square root, since length cannot be negative.

Answer 8

so i was right, right?

Answer 9

it is sqrt(82)

Answer 10

thank goodness!
