Help!

OpenStudy (anonymous):

Find the length of the unknown side of the triangle. |dw:1429057020545:dw|

OpenStudy (anonymous):

I assume it wants me to use \[a ^{2}+b ^{2}=c ^{2}\]

Nnesha (nnesha):

^^

Nnesha (nnesha):

go ahead and finish it!!

OpenStudy (anonymous):

so the answer would be 6\[\sqrt{3}\]

OpenStudy (anonymous):

\[6\]

OpenStudy (anonymous):

ahh it wont work

OpenStudy (anonymous):

\[6\sqrt{3}\]

Nnesha (nnesha):

how did you get 6 outside the root ?

OpenStudy (anonymous):

b=±6i3√

OpenStudy (anonymous):

most of the answers from other question I have done, want me to type the exact answer, using radicals

Nnesha (nnesha):

yeah but i'm asking why did you put 6 out side the parnetheses and 3 under the square root ??

OpenStudy (anonymous):

what do you mean?

OpenStudy (anonymous):

is that incorrect

Nnesha (nnesha):

like a^2 + b^2 = 18 right ?

OpenStudy (anonymous):

\[12^{2}+b ^{2}=6^{2}\]

Nnesha (nnesha):

nope c is the biggest side of right triangle |dw:1429057501326:dw| so you have to find c

Nnesha (nnesha):

|dw:1429057533348:dw|
