<h3>
Answer: 20 sides</h3>
==================================================
Work Shown:
x = exterior angle
9x = interior angle
interior + exterior = 180
9x+x = 180
10x = 180
x = 180/10
x = 18
n = number of sides
n = 360/x
n = 360/18
n = 20
There are <u>20</u> sides to the regular polygon.
Side notes:
- The formula to determine n only works for regular polygons.
- A polygon with 20 sides is known as an icosagon.
- Any pair of adjacent interior and exterior angles are supplementary. They add to 180 degrees.
Answer:
I'm talking about the boxes:
1st-false, there are 7/19, which is not more
2nd-true, there are 12/19 which is the most
3rd-true, 12/20 of the women like dancing
4th-false, 7/20 like dancing
5th-true, 13/20 don't like dancing
Answer: A) y= -1/2x+5
Step-by-step explanation: If the line is perpendicular to the original, the new "m" (coefficient of x) has to be the negative reciprocal of the original "m"
I'm pretty sure the answer is 12.
The 3rd one I thinkkkkk ??
