We calculate the sum of all interior angles using this formula 180(n-2) , n=number of sides
180(40-2)= 6840
6840 ÷ 40 = 171
Answer:
7
Step-by-step explanation:
the median is the number in the middle of a sorted array
here it has 10 numbers, so the median will be the average of the 5th and the 6th number
the 5th number is 7 and the 6th number is 7
the average is (7+7)/2 = 7
so the median is 7
23=8x-9 It’s says g(x)=23 so put 23 where
+9 +9. The g(x) is on the equation.
First, add the 9
32=8x
/8 /8. Then, divide by 8.
4=x. And this should be your answer
Hope this helps! :)
The mistake was is he subtracted at the end instead of dividing, the answer is 5/7
