If a regular polygon is 2340°, then how many sides does it have?

FORMULA: (n-2)180=sum of the interior angles.  

Where n=number of angles of a regular polygon.

We know that the sum of the interior angles is 2340

so

(n-2)180=2340 divide both sides by 180 and get

n-2=13 add 2 to both sides and get

n=15 Therefore, this polygon has 15 sides

the equation to find the number of sides is (n-2)x 180 = total number of degrees.

since you know the shape has a total of 2340 degrees, plug it into the equation. watch my steps:

(n-2)180= 2340

n-2=13

n=15

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
