Answer 1

Hi @Reilly208. Do you know of the Pythagorean theorem?

Answer 2

A^2 + B^2 = C^2

Answer 3

you have A and C

Answer 4

square them both subtract C^2 with A^2 and you get B^2

Answer 5

then square root it and you get B ;)

Answer 6

doesnt matter what side is which variable for all we care it can be E^2+G^2=O^2 :l

Answer 7

Well basically, with any right triangle, you can label the sides (in any order) a, b, and c.

Then following the Pythagorean Theorem: a^2 + b^2 = c^2, you can find the missing side, if given two of any of the other sides!

Answer 8

so \[a ^{2}+15^{2}=17^{2}\]

Answer 9

mhmm

Answer 10

Well right! But to make it easier... Let's label it like this!

Answer 11

what?

Answer 12

So its 17^2 + 15^2 = c^2 lol

Answer 13

no thats wrong it would need to be - not +

Answer 14

because "c" would be bigger than A then.

Answer 15

No I just moved around the a, b, and c =0P

Answer 16

would it be 8?

Answer 17

yes

Answer 18

awesome :)

Answer 19

@Cosmichaotic you cant do it that way tho because then the "c" would be bigger than "a"

Answer 20

Well let's see: 17^2 + 15^2 = c^2

So c^2 = 514 and taking the sqrt of both sides... yes 8!

Answer 21

well i got 22?

Answer 22

Wait, I did too lol

Answer 23

so that means you cannot do it that way :l

Answer 24

So I guess c has to be the hypotenuse?

Answer 25

yep

Answer 26

because the hypotenuse is always the bigger number and if you one side with the hypotenuse then itll probably be wrong :P

Answer 27

numbers*

Answer 28

Alright! @Reilly208 When you label your right triangle, make sure the two shortest legs are a and b, and the longest (hypotenuse) side is labeled c.
