The best approach to this is to use the law of cosine which is stated as
c2 = a2 + b2 â’ 2ab cos(C)
distance a=176.27; distance b=222.34; angle C=38.59; distance c is the missing value.
Hence c²=176.27²+222.34² -2*176.27*222.34cos38.59°= 138.71 miles
Answer: A. 6.5
Step-by-step explanation:
Here, the given set = { 15, 19 3, 12, 17, 2, 2, 8}
Mean, 
Number of elements, n = 8
Thus, the standard deviation, 
⇒ Option A is correct.
Hello,
Your answer would be 12.5. If you notice. 1.25 is more little than 12 flat. So sense 12.5 is almost 12,isn't 12 bigger than 1. So your final answer to this question would be 12.5.
Hope this helps
