What is the sum of the exterior angles, one at each vertex, of a polygon with 20 sides?A.20B.360C.180D. We need more information
ale4655 [162]

The measure of an exterior angle in a polygon with n sides is given by:

a_n=\frac{360}{n}

So, for n = 20, we have the measure of the exterior angles of the polygon with 20 sides:

\begin{gathered} a_{20}=\frac{360}{20} \\ a_{20}=18\degree \end{gathered}

Now, to find the sum of all exterior angles, let's multiply the exterior angles by the number of sides of the polygon:

\begin{gathered} S_{20}=a_{20}\cdot n \\ S_{20}=18\cdot20 \\ S_{20}=360\degree \end{gathered}

Therefore the sum is equal to 360°, correct option: B.

(The sum of exterior angles of a polygon with n sides is always equal to 360°)

The formula that describes this function is c = 50t

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let c represent the distance travelled at time t.

The cities are 200 miles apart and constant speed of 50mph, hence:

50 = c/t

c = 50t

The formula that describes this function is c = 50t

jenyasd209 [6]

Answer:

This is a 12.9% change - increase

Step-by-step explanation:

To find the percent change, use the percent change equation.

(New - Old)/(Old) * 100 = Percent Change

(525 - 465)/(465)*100 = Percent Change

60/465 * 100 = Percent Change

.129 * 100 = Percent Change

12.9% = Percent Change
