What Is The Formula For The Number Of Sizes Of A Regular Polygon If The Measurement Of Each Interior Angle Is Given?

what is the formula for the number of sizes of a regular polygon if the measurement of each interior angle is given?

 

Answer:

Formula:

Given measure of an interior angle = (n-2)(180)/n

Where n = number of sides

Step-by-step explanation:

Application of the formula:

Given measure of an interior angle of a polygon: 108°

To find the number of sides (n) of the regular polygon:

108 = (n-2)(180)/n

108n = (n-2)(180)

108n = 180n - 360

180n - 108n = 360

72n = 360

72n/72 = 360/72

n = 5

Therefore, the number of sides of a regular polygon given the measure of each interior angle at 108° is 5.

The regular polygon with 5 sides is pentagon.

Deforestation And The Burning Of Fossil Fuels Have Impacted Global Temperatures And Increased Atmospheric Co2 Levels. How Has This Affected Ocean Curr

Deforestation and the burning of fossil fuels have impacted global temperatures and increased atmospheric CO2 levels. How has this affected ocean currents and acidified the ocean? What are some consequences of ocean acidification?   Answer & Explanation: It affects our seawater by making it more acidic and causes carbonated ions to be relatively less abundant because our ocean absorbs 30% of CO2 in the atmosphere and when the level of CO2 increases, the CO2 in the ocean also increases which results to a series of chemical reactions that increases the production of hydrogen ions. Ocean acidification may lead to the destruction of marine life because the increase in the acidity of the seawater makes it harder for corals to build it skeletons which is particularly important beacuse they provide a home for many other sea creatures.
