Answer:
Below in bold.
Step-by-step explanation:
That would be 4/15 * 360 as there are 360 degrees in a circle
= 96 degrees.
Where is the question? reply to my comment and i can help :)
The equation could be used to calculate the sum of the geometric series is 
<h3>Sum of geometric sequence</h3>
Geometric sequence are sequence that increase expoentially. The formula for calculating the sum of an exponential sequence is expressed as:

where
- a is the first term
- n is the number of terms
- r is the common ratio
From the given sequence
a= 1/3
r = 2/9 * 3 = 2/3
Substitute into the formula

Hence the equation could be used to calculate the sum of the geometric series is

Hello! And thank you for your question!
Use Pemdas to get
3^(n+2)*4=3^28
Rewrite the equation:
3^4(n+2) = 3^28
Cancel the base of 3:
4(n + 2) = 28
Then divide 4 on both sides:
2 + n = 28/4
Simplify 28/4:
2 + n = 7
Subtract 2 on both sides:
n = 7 - 2
Finally simplify 7 - 2:
n = 5
Final Answer:
n = 5
