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
Answer:
The solution is obtained by dividing the number of flowers by the number of vases.
Step-by-step explanation:
The story problem is very straightforward. Normally, you need to read the problem and understand it.
Let's look at the question again.
Although we do not have all the quantities, we can still show how to solve the problem.
Let x be the total number of flowers.
There are 4 vases.
Therefore, the number of flowers in each vase will be:
x/4
Flow the same rule for similar problems.
