Answer:
D
Step-by-step explanation:
First we will find the total measure of all the interior angles:
180(n-2)
180(5-2) = 540
So the sum of the interior angles is 540.
Now add all the angles and set them equal to 540
84 + 12x + 92 + 9x - 16 + 13x + 6 = 540
166 + 34x = 540
34x = 374
x = 11
x is 11
Hope this helps :)
19.00 because 9.23 divided by .48 is 19.22 and rounded up would equal 19 considering the number behind the decimal is behind 0
I would think n+1 but I’m not sure
