From the pie-chart given, the best estimate for central angle for the leading cause which is "Human Error" is: B. 165 degrees.
The leading cause of train derailment will be the cause on the pie-chart that has the largest sector.
From the pie-chart given, the largest sector in the diagram is the sector for "Human Error."
This means that the leading cause is definitely "Human Error."
The central angle of the sector for "Human Error." is between 90 degrees and 180 degrees. That's less than half a full circle and less of a quarter circle. The best estimate from the given options is <u>165 degrees.</u>
Therefore, from the pie-chart given, the best estimate for central angle for the leading cause which is "Human Error" is: B. 165 degrees.

2l + 2w = 344
2(3w+8)+2w = 344
6w+16+2w=344
8w=328
width=41
Then plug back into the perimeter equation
2l + 2(41)=344
2l + 82 = 344
2l= 262
length=131
Answer:
$132.63
Step-by-step explanation:
$49.13 - ($32.50 × 2)
$49.13 - $65 = $-15.87
