The smallest degree that you can rotate a pentagon is 36 degrees
Sum of the First n Terms of a Geometric Sequence
Given a geometric sequence (or series) with a first-term a1 and common ratio r, the sum of the first n terms is given by:
We are given the series:
Before calculating the required sum, we need to find the common ratio. It's defined as the division of two consecutive terms. For example, using the first two terms:
The first term is a1 =120. Now apply the formula:
Operating:
Calculating:
Answer:
56
Step-by-step explanation:
The formula for finding the area of the circle works because they made it especially for it. I don’t really know how else to describe it, it simply just works.
