The measure of each exterior angle of a regular 15-side polygon is
24°
Step-by-step explanation:
In any regular polygon
- All sides are equal in lengths
- All angles are equal in measures
- The measure of each interior angle =
, where n is the number of its sides - The measure of each exterior angle =

- The interior angle and the exterior angle at any vertex are supplementary
∵ The polygon is regular
∵ It has 15 sides
∴ n = 15
∵ The measure of each exterior angle = 
∴ The measure of each exterior angle = 
∴ The measure of each exterior angle = 24°
The measure of each exterior angle of a regular 15-side polygon is
24°

Answer:
x≤13
Step-by-step explanation:
-4+x≤9
Add 4 to each side
-4+4+x≤9+4
x≤13
Answer:
1/36
Step-by-step explanation:
There are 6 numbers on a die. You have a 1/6 chance of rolling a 3 and a 1/6 chance of rolling a 4. 1/6 times 1/6 = 1/36.
First equation:
5(x+1)=20 —— distribute the 5 to the x and 1
5x+5=20 ——- subtract 5 from 20
5x=15 ———— divide by 5 from both sides
X=3 ————— answer
Second equation:
5x+1=20——— subtract 1 from 20
5x=19 ———— divide by 5 from both sides
X=19/5———— answer in fraction form
X=3.8————- answer in decimal form
