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

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

... 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
