Its not A and its not D. Its B or C. I think its C.
I hope this helped.
Answer:
AC is about 41. 095 miles long.
Step-by-step explanation:
You can use the Law of Cosines to solve this: c^2 = a^2 + b^2 – 2ab cos(C)
Substitute in your values, and you're good to go!
c^2=16^2+28^2-2(16)(28)(cos(117))
c^2 = 256 + 784 - 896(cos(117))
c = sqrt(1040 - 896(cos(117)))
c is about 41. 095 miles long.
Answer: 14
Step-by-step explanation:
We arrange the number as -3, 1, 7, 8, 18, 19, 42, the old median is 8.
But the median has change to 11 when the number is add, which means that the number is between 7 and 18.
(8 + x)/2 = 11 Where x is the new number
8 + x = 22
x = 14
This is a geometric series
r = 4
a1 = 0.25
n = 5
