Sum of interior and exterior angle is 180 so
Interior angle =180−72=108
Now we need to find the no of sides of the polygon= n We know that interior angle of n-sides is given by
(n−2)×180n
We have
(n−2)×180=108n
or
180n−360=108n
or
72n=360
n=5 sides so there are 5 angles each of 108 degrees Sum of the interior angles=108+108+108+108+108=540.....
<span>To find the measure of each exterior angle of a regular polygon, you just divide 360 degrees by the number of sides.

Answer:
each side is 17.2 feet
Step-by-step explanation:
a heptagon has 7 sides. 120.4 divided by 7 is 17.2. tell me if i am wrong. otherwise, hope this helps :)
Answer:
1. yes
2. no
3. yes
Step-by-step explanation:
A monomial is one term.
1. Yes. 7b is one term.
2. No. 5x-11 is not one term. It is 2 terms.
3. Yes. 2020 is one term.
8.1• 10^10. U need to move the decimal to the right 10 places. Then compare from the other things from the problem.
Answer:
8:100
Step-by-step explanation:
So if they sold 100 games, and 8 of those were board games then the ratio of board games to total number of games would be..
8:100
