Answer:

C. 15 votes

Step-by-step explanation:

B= votes Billy got

K = votes Keeton got

B = 3K

B+K =20

Substitute the first equation into the second equation

3K + K =20

Combine like terms

4K =20

Divide both sides by 4

4K/4 = 20/4

K =5

Given the regular octagon shown below, what is the measure of angle x?

vladimir1956 [14]

Answer:

$x=45$ °

Step-by-step explanation:

The angle shown in the figure is known as an external angle.

Also, in a regular polygon (like the regular octagon) the sum of all the exterior angles is the same regardless of the number of sides of the figure:

$360$ °

And to find the measure of a single external angle (such as the angle $x$ shown in the figure) we must divide 360 ° by the number of sides n:

$\frac{360}{n}$

and for the regular octagon, since it has 8 sides:

$n=8$

so the value of x is:

$x=\frac{360}{n}\\ \\x=\frac{360}{8}\\ \\x=45$ °

the measure of angle x is 45° which is the second option
