1.97=197%
The function A(n) = 22(1.1)^n-1 is an illustration of a geometric series
The sum of the 23rd through 40th terms of the series is 17.49
<h3>How to determine the sum of the
series</h3>
The nth term of the geometric series is given as:
The nth term of a series is represented as:
So, by comparison;
We have:
The sum of nth term of a geometric progression is:
Start by calculating the sum of the first 22 terms
Next, calculate the sum of the first 40 terms
Subtract S22 from S40
Hence, the sum of the 23rd through 40th terms of the series is 17.49

First solve for the other angles.
You know one angle is 15º.
The one across from it is also 15º since it is a vertical angle to the known 15º angle.
Both of those together gets 30º.
The whole thing is 360º, so just subtract 30 from 360 and divide.
360 - 30 = 330
Do the same for the 15x angle.
The one under/across to it is a vertical angle so is also 15xº.
Now you are left with 30xº = 330.
Just divide now.
330 / 30 = 11
x = 11
15x = 165
Checking your work:
15x = 165
15x = 165
15
15
Those are the angles.
Add those numbers together and make sure it adds up to 360º.
165 + 165 + 15 + 15 = 360
So this is correct.
