aidenj:

need help badly

snowflake0531:

So let's first find the diagonal of hte full square To do that, we first need the side lengths since a is 4 and b is 3, what is the whole length of it

aidenj:

7 right?

snowflake0531:

Yes so we have the square 7 x 7 So to find the diagonal, use the pythagorean theorem, and make 7 and 7 the two sides Can you set up the equation?

aidenj:

idk

aidenj:

bc they the saem number

snowflake0531:

\[7^2 + 7^2 =c^2 ~~find~c\]

aidenj:

14

aidenj:

wait is that the answer

snowflake0531:

... what is 7^2

aidenj:

14

snowflake0531:

.. no 7^2 is 7 times 7

aidenj:

so 49

snowflake0531:

Congrats on orange o-O

aidenj:

tys

snowflake0531:

But yes so we then we have 49 + 49 =c^2 simplify that

aidenj:

98^2

snowflake0531:

No it's just 98

aidenj:

ok

snowflake0531:

so 98 = c^2 so c = sqrt98 Can you put sqrt98 into a calculator?

aidenj:

9.8

snowflake0531:

Actually it would round to 9.9

aidenj:

k is that the first box orlast

snowflake0531:

first

snowflake0531:

Now for the second one We have to find length c we know that a and b are 4 and 3, which means that c must be 5

aidenj:

k

snowflake0531:

So do the same thing \[5^2 + 5^2 = c^2\]

aidenj:

10*2+10*2 then right

snowflake0531:

... what did i just say.... the exponent means it multiplies by itself 5^2 is 5 times 5

aidenj:

no 5 times 5

aidenj:

25

snowflake0531:

so 25 +25 =c^2 what is c^2

aidenj:

50

snowflake0531:

Yes so c^2 =50 so c=sqrt50

aidenj:

7

snowflake0531:

it rounds to 7.1

aidenj:

ok tys

snowflake0531:

yw

aidenj:

couldnt have done it without u
