interior angle of a regular 18-gon.
It is easier to calculate the exterior angle of a regular polygon of n-sides (n-gon) by the relation
exterior angle = 360/n
For a 18-gon, n=18, so exterior angle = 360/18=20 °
The value of each interior angle is therefore the supplement, or
Interior angle = 180-20=160 degrees.
Naming of a 9-gon
A polygon with 9 vertices is called a nonagon (in English) or enneagon (French ennéagone, but the English version is sometimes used)
You had a good start with the correct answer.
Exterior angle of a 15-gon
The exterior angle of a 15-gon can be calculated using the relation given in the first paragraph, namely
Exterior angle = 360/15=24 degrees
6 is in the ones place
.5 is in the tenths place
and the 4 in 6.54 is in the hundredths place
Answer:
2580 degrees rotated per second
Step-by-step explanation:
since you have to find the degrees it rotates per second.
you need to divide 430 by 60 to find rotations per second
1) 430/60
= 7.16666667 rotations per second
-then you have to multiply it by 360 degrees ,because their is 360 degrees in a circle
2) 7.16666667 (360)
= 2580 degrees rotated per second
