Based on pythagoras' theorem, how would you explain the structure of the egyptian pyramids?

It is known to us that the Eqyptian pyramids have a square-shaped base and four sides which are equilateral triangles. The angles formed between the edge of the base and the equilateral side is 90°, thus, we can clearly apply the pythagorean theorem. 

A = Quartile 1 = 74.725

B = Median (quartile 2) = 80.25

C = Quartile 3 = 82.125

D = Minimum = 74.1

E = Maximum = 82.7

Step-by-step explanation:

The values for the data for the average life expectancy are as follows;

North Carolina                    79.6  

Oregon                                82  

District of Columbia           77.9

Nevada                               81.3  

New York                           82.5  

Colorado                            80.9  

Alaska                                74.9  

Connecticut                       82.7  

Montana                            74.1  

Mississippi                         74.2  

Sorting the data we have;

74.1

74.2

74.9

77.9

79.6

80.9

81.3

82

82.5

82.7

The minimum value is 74.1

The maximum value is 82.7

The 1st quartile is the term or 74.725

The median 2nd quartile is the term and the value is 80.25

Third quartile value is the term or 82.125.
