Will medal use Pythagorean Theorem

OpenStudy (adi3):

OpenStudy (anonymous):

This is easy

OpenStudy (adi3):

@butterflydreamer need help

OpenStudy (sleepyjess):

Do you know what to Pythagorean Theorem is first?

OpenStudy (sleepyjess):

*what the

OpenStudy (anonymous):

The Pythagorean Theorem says that a^2 + b^2 = c^2

OpenStudy (sleepyjess):

-_-

OpenStudy (anonymous):

Oh, hehe.

OpenStudy (sleepyjess):

Ok, well since he gave us that, c is always the hypotenuse, a and b are the legs

OpenStudy (adi3):

I know a^2 + B^2 = C^2

OpenStudy (anonymous):

We already have our hypotenuse, so we need to find the value of the other leg.

OpenStudy (anonymous):

So first, square both of the numbers.

OpenStudy (anonymous):

6.5^2 and 2.7^2 Do that. What do you get?

OpenStudy (adi3):

6.5^2 = 42.25 2.7^2 = 7.29

OpenStudy (anonymous):

Yes!

OpenStudy (anonymous):

Then add them up.

OpenStudy (adi3):

49.54

OpenStudy (sleepyjess):

Why are you adding them?

OpenStudy (anonymous):

I thought I did something wrong...

OpenStudy (sleepyjess):

We need to find b^2

OpenStudy (adi3):

u hve to pert of the Pythagorean Theorem

OpenStudy (sleepyjess):

not c^2

OpenStudy (anonymous):

@sleepyjess We don't have b^2

OpenStudy (sleepyjess):

I know

OpenStudy (anonymous):

We only have a^2 and c^2

OpenStudy (adi3):

49.54

OpenStudy (anonymous):

It gives us the value of the hypotenuse and the value of one leg.

OpenStudy (igreen):

We have b^2 or a^2, not both.

OpenStudy (anonymous):

Yes, then square root that. @Adi3

OpenStudy (sleepyjess):

Right now we have \(7.29+b^2 = 42.25\). We need to subtract 7.29 from both sides

OpenStudy (anonymous):

?????????

OpenStudy (sleepyjess):

AMQ is solving as if we have a and b and we need to find c

OpenStudy (adi3):

I get 7.03 but the answer says 5.9

OpenStudy (anonymous):

:/

OpenStudy (igreen):

Looks like you guys are confused..

OpenStudy (sleepyjess):

@AnswerMyQuestions , you are solving \(7.29+42.25 = c^2\)

OpenStudy (igreen):

\(2.7^2 + b^2 = 6.5^2\)

OpenStudy (anonymous):

:/

OpenStudy (anonymous):

*Slaps forehead*

OpenStudy (sleepyjess):

LOL

OpenStudy (adi3):

I got it

OpenStudy (igreen):

Okay, tell us what you got.

OpenStudy (sleepyjess):

Ok, @Adi3 , would you like to just restart this or go from \(7.9+b^2=42.25\)

OpenStudy (adi3):

5.9

OpenStudy (igreen):

Correct

OpenStudy (sleepyjess):

yes

OpenStudy (sleepyjess):

whew, AMQ even had my mind spinning for a minute

OpenStudy (igreen):

\(2.7^2 + b^2 = 6.5^2\) \(7.29 + b^2 = 42.25\) \(b^2 = 34.96\) \(b = \sqrt{34.96}\) \(b \approx 5.9\)

OpenStudy (adi3):

7.29 - 42.25 = 34.96 square of 34.96 = 5.9

OpenStudy (igreen):

\(\Huge\color{lime} \checkmark\)

OpenStudy (sleepyjess):

should be 42.25-7.9, but you get the idea :P

OpenStudy (igreen):

7.29*

OpenStudy (sleepyjess):

^^^

OpenStudy (adi3):

yes, I get the idea thank u guys

OpenStudy (igreen):

So many mistakes xD

OpenStudy (sleepyjess):

No problem haha :)
