Question

If s = 7 cm and t = 24 cm, what is the length of r?
(The shape is a right triangle)

Answer 1

Ok So you are saying that we have a right triangle and one side has a length of 7 another of 24 and we would liek to find the length of the hypotnuse?

Answer 2

I'm guessing this is your triangle?

Answer 3

yes and yes

Answer 4

Hmmmm @doulikepiecauseidont ya think r is the hypotenuse??? maybe t is?

Answer 5

yes I do @swissgirl

Answer 6

This is a Pythagorean triple

Answer 7

it looks more like this, i dont know if that changes anything...

Answer 8

Plus, they never specified what side goes where, so I'm allowed to assume this

Answer 9

Ya that is a better representation but we get the picture. I just would like to know how you knew that r was the hypotenuse ... Im curious

Answer 10

Who said you can assume?

Answer 11

The questioner did, I asked if that was her triangle and she said yes, if it wasn't then I would've changed it lol

Answer 12

ohhh ok gotcha

Answer 13

so whats the answer?

Answer 14

You have to use the Pythagorean theorem : \[\Large \color{blue}{s}^2+\color{blue}{t}^2=\color{red}{r}^2\]

Answer 15

so 49+576=625?

Answer 16

Now you have found r^2

Answer 17

so its 62^ or just 625?

Answer 18

625^*

Answer 19

r^2=625
you have to take the sqrt of both sides

Answer 20

so whats the answer...

Answer 21

You have the answer multiplied by itself (r times r)

Answer 22

take the sqrt of both sides

Answer 23

r times r=r^2

we just want r so we have to take the sqrt

Answer 24

and the sqrt is?...

Answer 25

31?

Answer 26

is 31 times 31 equal to 625?

a number is the square root (sqrt) of another number if you multiply that number by itself and get the number in question:

e.g., 2 is th sqrt of 4 cause 2 times 2=4

Answer 27

oh okay so its 25?

Answer 28

Correct!

Answer 29

thats the final answer?

Answer 30
