10)
(n-2) x 180 = 2160
n - 2 = 12
n = 14

answer
C. 14

11)
interior angle = [(11 - 2) x 180] / 11
= (9 x 180) / 11
= 1620/11
= 147.27

exterior angle = 180 - 147.27 = 32.72

12)
heptagon  has 7 sides, n = 7
interior angle = [(5 x 180)/7 = 900 / 7  = 128.57

-14n + q=rt-4n, for n
pentagon [3]
N = -1/10rt + 1/10q
= −14n+q+4n=rt−4n+4n
= −10n+q=rt
= −10n+q+−q=rt+−q
= −10n=rt−q
= -10n/-10 = rt-q/-10
So the answer is:
= n = -1/10rt + 1/10q

Is 3/8 greater than 7/12​
Gennadij [26K]

Answer:no

Step-by-step explanation:put the two numbers in the same denominator

The least common denominator of 8 and 12 is 24. So to get 8 to 24 you multiply it by 3. So 3(3/8) is 9/24.

To get 12 to 24 you multiply it by 2. So 2(7/12) is 14/24. 9/24 is less than 14/24.
