To solve this question, you can subtract the amount of rainfall that fell in a year from the average amount of rainfall.
For this question, 38-29.777 is 8.223.
Answer: Aₙ = Aₙ₋₁*3; where A₀ = 2.5
Step-by-step explanation:
Let's try with some known sequences:
Arithmetic.
The difference between consecutive terms is constant:
7.5 - 2.5 = 5
22.5 - 7.5 = 15
We can already see that it is not an arithmetic sequence.
Geometric:
The ratio between consecutive terms is constant.
7.5/2.5 = 3
22.5/7.5 = 3
67.5/22.5 = 3
...
We can already see that this is a geometric sequence.
Then we can write the n-th term as:
Aₙ = Aₙ₋₁*3, where A₀ = 2.5
To find the interior angle of C, you must subtract 117 (the exterior) from 180 (a straight lines angle) to find the interior angle
Angle C = 63.
180 - 65 (angle a) - 63 (angle c) = 52 (angle b)
Angle B = 52

Answer:
The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded part can occur in two ways in polygons.
