find the value of x in the figure below 139 9x 71 5x 92
1. x = 16
2. x = 17
How do you determine the value of X?
Find X, where X is a barely visible but vast tragedy.
2. Find X, where X is a barely visible way to create a vast amount of value.
Step-by-step explanation:
1. The sum of the exterior angles of any polygon is 360 degrees. So, to find x, we can add up all of the angle measures and set them equal to 360, then solve for x:
46 + 93 + 47 + 4x + 62 + 3x = 360
Combine like terms:
248 + 7x = 360
Subtract 248 from both sides of the equation to isolate 7x:
7x = 112
Divide both sides by 7 to find the value of x:
x = 16
2. The sum of the interior angles for a 5-sided polygon is 540 degrees. So, to find x, we can add up all of the angle measures and set them equal to 540, and then solve for x:
5x + 139 + 9x + 71 + 92 = 540
Combine like terms:
14x + 302 = 540
Subtract 302 from both sides to isolate the 14x:
14x = 238
Divide both sides by 14 to find the value of x:
x = 17

The number of young drivers involved in motor vehicle
crashes each year has declined substantially in recent
years, for teenage drivers of all ages and in crashes of all
severities. The number of people injured annually in
crashes involving teen drivers declined by 51% between
1994 and 2013, and the number killed each year in teen
driver crashes declined by 56%. Most of the decline in
injuries and virtually the entire decline in fatalities
occurred between 2004 and 2013. While the reasons for
the declines are not entirely clear, numerous studies have
shown that strong state GDL systems have contributed
substantially to reductions in injury and fatal crashes of
drivers aged 15-17. Research also suggests that economic
factors including rising gas prices and the economic
recession of 2008 resulted in substantial declines in teen
driving and thus teen crashes as well.

D: Though I don't like choosing this as an answer, there does not seem to be any other choice. I would pick D. because AAA is an organization that is dedicated to studies that show what driver trends are and how they are noticeably evolving. The problem is, we really don't know who wrote it and the facts and figures are not footnoted in any way. Still D is the best answer.
B: though I agree that having an anonymous author is a problem, it is not a huge one. Still it would help to know who the author is, and how well known is he/she to others in the field.
C: Of course the author is biased. He/She has been commissioned by AAA to write this summary. But it is not the best statement that can be made. D is.
