The 2 angles at a vertex are supplementary (one interior and one exterior) the exterior angle is = the the sum of the 2 remote interior angles..
The given condition is an arithmetic sequence with the first term (a1) is 1 penny and the common difference (d) is 1 penny. A year that is not a leap year has 365 days (n). The arithmetic series (S) is calculated through formula,
S = (n/2) (2a1 + (n - 1) x d)
Substituting the known values,
S = (365/2) (2 x 1 + (365 - 1) x 1)
S = 66795 pennies
A dollar is 100 pennies. Therefore, at the end of the year, the total savings is $667.95.
Quick Answer: 36 + 10h
Long explanation below
Alright, as we can see in the question, it's asking you to use the commutative property (of addition, 'cause that's the operation being used).
We know that this property states that you can move terms around in an addition problem and still get the same result.
So since there are only two terms in the expression given, you can just switch the terms around, giving you..
36 + 10h.
