Answer 1

pythagorean theorem

Answer 2

:( i fail at this :p

Answer 3

the square of the 2 legs will equal the longest side
we have the 2 legs and we're trying to find the hypotenuse, x

Answer 4

oh yeah my bad

Answer 5

so \(30^2+20^2=x^2\)

Answer 6

1300

Answer 7

<3 thanx

Answer 8

not yet bby

Answer 9

\(30^2+20^2=x^2\\900+400=x^2\\1300=x^2\\x=\sqrt{1300}\)

Answer 10

you solved for x^2 but we need x

Answer 11

so divide by 2
or by itself

Answer 12

take the square root
square roots and squaring are inverse operations. one undoes the other

Answer 13

so just plug in \(\sqrt{1300}\) into a calculator

Answer 14

so technically 36

Answer 15

indeed

Answer 16

:) your the best <3

Answer 17

you're* :p
