anonymous · Answer

Is this a right triangle?

anonymous · Answer

yeah so use the m^+n^=l^ right?

solomonzelman · Answer

|dw:1422236926327:dw|like this?

anonymous · Answer

yes

solomonzelman · Answer

Okay, so for any such a triangle with a hypotenuse of l, you would have that:
$\large\color{slate}{ \displaystyle  m^2+n^2=l^2 }$

solomonzelman · Answer

you are given the m and the n.... go for it

solomonzelman · Answer

m=35
n=37

anonymous · Answer

1225+1369=?

anonymous · Answer

2594

anonymous · Answer

@SolomonZelman  is that the final answer?

solomonzelman · Answer

yes, so you have: $\large\color{slate}{ 2594=l^2  }$
it is not yet a final answer

solomonzelman · Answer

you need to take the square rot of both sides to find the length of l.

anonymous · Answer

the sr of both sides are 5.9 and 6.0?

solomonzelman · Answer

$\large\color{slate}{ 2594=l^2  }$   is what we have so far, correct?

anonymous · Answer

yes

solomonzelman · Answer

$\large\color{black}{ 2594=l^2 }$

taking the square root on both sides,

$\large\color{black}{ \color{red}{\sqrt{\color{black}{2594}}}=\color{red}{\sqrt{\color{black}{l^2}}}  }$

solomonzelman · Answer

what do you get for the right side ?

anonymous · Answer

....50.9?

solomonzelman · Answer

yes, the left side
and the right side is.

solomonzelman · Answer

the right side is?

anonymous · Answer

i dont know

solomonzelman · Answer

$\large\color{black}{ \color{red}{\sqrt{\color{black}{x^2}}}=x  }$   for any number x.

solomonzelman · Answer

just like:   $\large\color{black}{ \color{red}{\sqrt{\color{black}{2^2}}}=2  }$

solomonzelman · Answer

So you are having:  $\large\color{black}{ l=\color{red}{\sqrt{\color{black}{2594}}}  }$
I think the intepretation was incorrect.

solomonzelman · Answer

maybe it is:
|dw:1422237546446:dw| ??

solomonzelman · Answer

it makes a big difference which side is the hypotenuse!

anonymous · Answer

The answer is 12!

solomonzelman · Answer

how do you know ?

solomonzelman · Answer

k, based on which interpretation of the question are you now going /

solomonzelman · Answer

?

anonymous · Answer

*correct or incorect
