Answer:
x = 130 degrees
Step-by-step explanation:
7-sided polygon = 900 degrees

770 + x = 900
<u>-770 -770</u>
x = 130

If n is rational, it means that

Therefore when we do n² we can write it as

Remember that the product of two integer numbers is also an integer, therefore we can guarantee that

Then we can confirm that n² is the quotient of two integers and the denominator is not zero, therefore, n² is always rational, it cannot be an irrational number
The area would be 18 inches and you would need a ten by ten square to cover it.
