<h3>
Answer: 20 sides</h3>
==================================================
Work Shown:
x = exterior angle
9x = interior angle
interior + exterior = 180
9x+x = 180
10x = 180
x = 180/10
x = 18
n = number of sides
n = 360/x
n = 360/18
n = 20
There are <u>20</u> sides to the regular polygon.
Side notes:
- The formula to determine n only works for regular polygons.
- A polygon with 20 sides is known as an icosagon.
- Any pair of adjacent interior and exterior angles are supplementary. They add to 180 degrees.
Answer:
2n^{2} +2n
INSERT
Step-by-step explanation:first you want to move the negative which is negative 1 into the set of parenthesis and then Foil the two parenthesis together and the combine like terms
It would be 76 degrees because it’s a vertical angle
The data that can be identified from the box plot are Minimum and Median
<h3>How to determine the data that can be identified from the box plot?</h3>
The box plot is used to determine the five-number summary
The five-number summaries are:
- Minimum
- Lower quartile
- Median
- Upper quartile
- Maximum
From the list of options, we have:
Minimum and Median
Hence, the data that can be identified from the box plot are Minimum and Median
