This is easy

@butterflydreamer need help
OpenStudy (sleepyjess):
Do you know what to Pythagorean Theorem is first?

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

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!

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

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

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 (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..

@AnswerMyQuestions , you are solving \(7.29+42.25 = c^2\)
OpenStudy (igreen):
\(2.7^2 + b^2 = 6.5^2\)
OpenStudy (anonymous):
:/

*Slaps forehead*
OpenStudy (sleepyjess):
LOL

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

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

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
