Step-by-step explanation:

3×3=9. 3 faces so 9×3=27

10×3=30. 4 faces so 30×4=120

6×3=18. 2 faces so 18×2= 36

15×3=45. 3 faces so 45×3= 135

120+135=255

36+27=63

255+63=318

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.

It gives 3 choices of toppings, and asks for the number of ways to arrange two toppings. Using the formula they give, n = 3 and k =2. So: $\frac{3!}{2!(3-2)!}$
Thus, the answer is 3.
