Let
S------> The sum of the measures of the interior angles of a polygon
n-------> number of sides of a polygon
we know that
The formula to find the sum of the measures of the interior angles of a polygon is equal to
°
in this problem
°
Solve for n

therefore
the answer is

Answer: 79%
That’s because it’s the middle probability it can’t be others because they are too high it too low
The new square has length: 10 + l, where l is the original length of the square, and it's area is (10 + l)^2;
So, we solve the equation: 3 x l^2 = (10 + l)^2;
Then, 3 x l^2 = 100 + 20 x l + l^2;
Finally, 2xl^2 - 20xl - 100 = 0; / ÷2;
l^2 - 10l - 50 = 0 (we use the quadratic equation formula);
The only positive solution is l = 5(1+ \sqrt{3} );
To compare the fractions we need to find a common denomanator.
This means we need to find a common number (to the denomanator) in each number set of times tables.
In this case we can use 6 as a common denomator.
One of out fractions is already out of 6 so we just need to convert the other one.
We can just double 4/3 to give us 8/6.
We can now compare the data, we have 8/6 and 8/6.
These fractions show that both John and Mya use the same amount of milk for their recipies, this being 8/6 or 1 1/3 as a mixed number.
The probability is likely but not impossible. there is a 4/5 chance she will not spend a four.
