6 is the answer
Reason:
Cuz ur mom said so
The formula A = 180(n-2)/n relates to the measure A of an interior angle of a regular polygon to the number of sides n. If an interior angle measures 120 degrees, find the number of sides
A)5
B)6
C)8
D)10
I have NO clue on how to do this pls help.
Make A equal 120 because A is the measure of an interior angle. Then solve the equation by cross multiplying. I hope that helps you.
I don't understand
change the formula around to find n:
A= 180(n-2)/n
nA= 180n-360
n(A-180)=-360
n= 360/(180-A)
so 6 is the correct answer? thanks for explaning it IF I'm right
six is right.
