@ShadowLegendX

OpenStudy (shadowlegendx):

What did you get?

OpenStudy (selena2345):

i got 0

OpenStudy (selena2345):

OpenStudy (selena2345):

@ShadowLegendX

OpenStudy (selena2345):

hello @ShadowLegendX

OpenStudy (selena2345):

where are you ? @ShadowLegendX

OpenStudy (shadowlegendx):

|dw:1400290317353:dw|

OpenStudy (shadowlegendx):

You would just use the Pythagorean Theorem here \[10^{2} + 10^{2} = C ^{2}\]

OpenStudy (shadowlegendx):

We would then get \[100 + 100 = C^{2}\]

OpenStudy (selena2345):

is the answer 14.2 ? @ShadowLegendX

OpenStudy (selena2345):

@ShadowLegendX

OpenStudy (selena2345):

@ShadowLegendX

OpenStudy (selena2345):

@ShadowLegendX

OpenStudy (shadowlegendx):

Ok So \[C ^{2} = 200\] Now if we ge the square root of 200, we have our hypotenuse

OpenStudy (shadowlegendx):

get*

OpenStudy (selena2345):

14.2 is the answer ? @ShadowLegendX

OpenStudy (selena2345):

right @ShadowLegendX

OpenStudy (shadowlegendx):

hmm let me try check...

OpenStudy (selena2345):

its 14.2 @ShadowLegendX

OpenStudy (shadowlegendx):

hmm ok

OpenStudy (selena2345):

its 14.2 right @ShadowLegendX

OpenStudy (shadowlegendx):

Btw in my earlier drawings I had put cm instead of in, just ignore that

OpenStudy (selena2345):

so its 14.2 right ? @ShadowLegendX

OpenStudy (shadowlegendx):

Not sure :/

OpenStudy (shadowlegendx):

|dw:1400291442933:dw|

OpenStudy (selena2345):

what

OpenStudy (selena2345):

its 14.2

OpenStudy (shadowlegendx):

|dw:1400291590088:dw| Yeah it's 14.2

OpenStudy (shadowlegendx):

I had missed the part where it was a "right triangle"

OpenStudy (shadowlegendx):

Could you show me the steps that you used to find 14.2 as C?

OpenStudy (selena2345):

|dw:1400291685530:dw|

OpenStudy (selena2345):

@ShadowLegendX

OpenStudy (shadowlegendx):

200 squared is 14.2? o-o

OpenStudy (selena2345):

square root of 200 is 14.14213562

OpenStudy (shadowlegendx):

14.14213562 x 14.14213562 = 199.999999894

OpenStudy (selena2345):

whatever

OpenStudy (shadowlegendx):

Haha Selena :)

OpenStudy (selena2345):

what

OpenStudy (shadowlegendx):

We I believe we found our answer, good luck @Selena2345

OpenStudy (shadowlegendx):

Well*

OpenStudy (selena2345):

what are you talking about ? @ShadowLegendX

OpenStudy (shadowlegendx):

The answer is 14.2 as \[14.2 \times 14.2 = 201.64\]

OpenStudy (selena2345):

Thank You So Much!!!!!! :) @ShadowLegendX
