12-x(5-4k)=y
12-y=x(5-4k)
12-y/(5-4k)=x
<span>Sum of Interior Angles: Formula: (n-2) * 180
-Pentagon: 540</span>°<span>
-Hexagon: 720</span>°<span>
-Octagon: 900</span>°<span>
-Nonagon: 1260</span>°<span>
-Decagon: 1440</span>°<span>
-Dodecagon: 1800</span>°
Each interior Angle: Formula: [(n-2)*180] / n
-Pentagon: 108°
-Hexagon: 120°
-Octagon: 135°
-Nonagon: 140°
-Decagon: 144°
-Dodecagon: 150°
The sum of the exterior angles of each polygon stated above is equal to 360 degrees. Using the formula: (180-interior angle) * n
The central angle is formed by making a circle in the middle and divide it by the number of sides. Therefore, CA = 360 /n
-Pentagon: 72°
-Hexagon: 60°
-Octagon: 45°
-Nonagon: 40°
-Decagon: 36°
-Dodecagon: 30°
A <u>central</u><u> tendency</u> is a value that describes the center of a data set and includes the mean, median, and mode.
And just in case you don't know:
Mean is the sum of all the numbers divided by how many numbers there are. Basically the average.
Mode is the number that occurs the most times.
Median is the middle number when you write the numbers from lowest to greatest.<u />
