Answer:
I think its C) 43. Let me know what you get
Where are the variables for the equation?
Answer:
x=3.5
Step-by-step explanation:
subract 5 on the other side, than divide by 2
The equation for this is (n-2) x 180
Replace n with the number of sides:
a. 9: (9-2) x 180 = 7 x 180 = 1,260
b. 19: (19-2) x 180 = 17 x 180 = 3,060
Answer:
Step-by-step explanation:
You should know that quotient is the result of division.
n/2
Four less than that would be subtracting.
(n/2) - 4 = 9
