answer:
52
step-by-step explanation:
- we can use the 45-45-90 triangle theorem for this: x, x, x
this is because this is a square
- squares have two sides of the same length, and the diagonal is different
- the x's stand for the sides, whereas the x stands for the diagonal
x = 26
x = 13
- now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4
13 X 4 = 52
Area of polygon ABCDE will be summation of all the areas of triangle = 7.95 + 9.8 + 8.75 = 26.5 square units.
Answer:
Step-by-step explanation:
During the calculation of any population standard deviation, the sum of the squared deviation is usually divided by N, which is the number of data entry in the population. Thereafter, the square root of the result would be taken.
On the other hand, during the calculation of the sample standard deviation, the sum of the squared deviations is usually divided by n - 1, with n being number of entries in the sample data set. Thereafter, the square root of the result would be taken.
