To the nearest degree what is the measure of each exterior angle of a regular dodecagon

malfutka [58]

Answer:

$30^{\circ}$

Step-by-step explanation:

We are asked to find the measure of each exterior angle of a regular dodecagon.

We know that a regular dodecagon is a 12 sided regular polygon with each side equal.

We know that measure of each angle of n-sided regular polygon can be found using formula:

$\text{Each exterior angle}=\frac{360^{\circ}}{n}$

Upon substituting $n=12$ in above formula, we will get:

$\text{Each exterior angle of a regular dodecagon}=\frac{360^{\circ}}{12}$

$\text{Each exterior angle of a regular dodecagon}=30^{\circ}$

Therefore, the measure of each exterior angle of a regular dodecagon is 30 degrees.

Lady bird [3.3K]

Hello,

I suppose you want the 4 numbers.

Let's call the numbers $2n,2n+2,2n+4,2n+6$
$2n+2n+2+2n+4+2n+6[=8n+12=15*4\\
8n+12=60\\
8n=48\\
n=6\\\\
2n=12\\
2n+2=14\\
2n+4=16\\
2n+6=18\\
