Given:
Sum of arithmetic sequence is 21.
Product of arithmetic sequence is 315.
I did a manual computation. Arithmetic sequence means that there is a constant difference between the two consecutive numbers.
x + (x+2) + (x + 2 + 2) = 21
3x + 6 = 21
3x = 21 - 6
3x = 15
x = 15/3
x = 5 1st number
x + 2 = 5 + 2 = 7 2nd number
x + 2 + 2 = 5 + 2 + 2 = 9 3rd number.
5 + 7 + 9 = 21
5 x 7 x 9 = 315

monday, tuesday, wednesday, thursday, friday, saturday, and sunday all have "a" in it so it has a 100% probability
To verify whether the diagonals are perpendicular to each other, we find the slope of each segment and we can see that the slopes should be opposite reciprocals of each other.This means, these segments are really perpendicular. This theorem can be verified through congruent angles present in the quadrilateral.
