I'll try to solve.

- anonymous

Will you give me a minute?

- anonymous

oops error
the question is easy use the pythogoread formula
c^2=a^2+b^2
white dr is c westerfield is b and blue is a
now we plug in.
144= blue^2 + 13^2
^ that is already squared for you.
^ that is westerfield.
Solve for blue. Do you know how?

- anonymous

on previous one i forgot to square the blue blvd one

- anonymous

Okay. Let me try to solve,alright?

- anonymous

ok :)

- anonymous

Thank you,sir.

- anonymous

so basically 144=a^2+13^2?

- anonymous

YES

- anonymous

Okay, ty. Let me solve for A now,then.

- anonymous

I got '5' as 'a^2'.

- anonymous

I think your diagram might be wrong tho

- anonymous

Really?

- anonymous

How's it wrong?

- anonymous

the longest street is suppose to be the c in the theorem.
white dr is sqrt (144)= 12 but westerfield is 13 which is longer.

- anonymous

No, that's how it is on my sheet. That's okay. i can leave it as is.

- anonymous

Good observation, though.

- anonymous

so... would it be '144=5^2+13^2'?

- anonymous

it is wrong either blue is longer. But for sure westerfield is longer.

- anonymous

5^2+13^2=194 nott 144 silly

- anonymous

Oh right i forgot to square it.

- anonymous

Sorry bout that...

- anonymous

wait wait wait..

- anonymous

how did you get 194?

- anonymous

you gave me 194
5^2+13^2
you gave that
25+169=194
You cant solve it until you fix the streets. You need to know the longest street. You cant just pick it.
white dr =12 but wester field is 13. 13 should be c
or blue but we dont even know what blue is. we can make blue c also to see if it works

- anonymous

Oh right....Okay.

- anonymous

Fine, whatever you think is best.

- anonymous

Let's make blue C.

- anonymous

make westerfield c and the numbers work better :)
c^2= b^2+b^2
169=144+b^2
^ wester field 13^2 is given so square it to get 169
^ white 144 was given and already squared
^ blue
now solve :)

- anonymous

Okay. So...

- anonymous

This might take a min or 2

- anonymous

solve for b

- anonymous

Yes,one second.

- anonymous

Is it 5?

- anonymous

yup

- anonymous

YESSSS!

- anonymous

|dw:1364431455866:dw|

- anonymous

I also got that the first time.

- anonymous

5 as the missing value, I mean.

- anonymous

Thank you very much for your assistance.

- anonymous

144 = a^2+13^2 --> a=5^2

- anonymous

no but it did not work out cuzz
you said
"so... would it be '144=5^2+13^2'?"
no
5^2+13^2=25+169 is not 144 what you were actually getting was imaginary result. a 5i.
what you did was something like this
144=a^2 +13^2 simplifies to
144=a^2+169 then you subtract 169 from both sides
144-169=a^2
-25=a^2 then you try to take sqrt of -25 but how? you cant take sqrt of negatives.
you can but it is out of your scope. Unless they taught you about imaginaries already.

- anonymous

no....

- anonymous

That was a long reply. LOL.

- anonymous

Thanks anyhow. So the final equation would be 169=144+b^2 --> b=5?

- anonymous

@timo86m help please

- anonymous

Yes now you just add up the lengths of the streets to see which is longer route.

- anonymous

Okay....

- anonymous

westerfield and blue =13+5 = 18
blue to white=5+12=17

- anonymous

there is a one mile difference.

- anonymous

yup :D lol you got ahead of me :) But anyhoo i think this is best.

- anonymous

Nope, you're way ahead of me.

- anonymous

I just did first grade subtraction.

- anonymous

So, how would you state the answer?

- anonymous

joe will run one mile further along his new route

- anonymous

ok.thanks!
