Answer:
Internal angle = 
Number of sides = 18
Step-by-step explanation:
Given that:
We have a regular polygon with number of sides unknown.
Measure of an exterior angle of the polygon = 
To find:
Measure of an interior angle and the number of sides of the polygon?
Solution:
Let us have a look at the relation of sum of external angles.
Sum of one internal angle and its corresponding external angle = 
Internal angle + external angle = 
Internal angle =
-
= 
Sum of all the external of a regular polygon = 
All the external angles will be equal because it is a regular polygon.
Let the number of sides = 
Therefore,

Therefore, the answers are:
Internal angle = 
Number of sides = 18
Answer:
58.3%
Step-by-step explanation:
125/300 people decided to buy their product but 175 didn't to get the answer for the problem you just divide 175 by 300 which gets you 0.58333... in which you move the decimal place two to the right which gives you 58.3 then that is your percent 55.3%
7^4 or 7 and a little 4 above it to the right like this...
You would divide 291/7 which would equal 41.5 so the answer is no 7 is not a factor of 291
