hope this helps .
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.

It's asking for the coordinates of the treasure and I can't really see it right but it looks like the coordinate is about (-0.5, 1.5) it's not exact though cuz I can't really see it
Hi there!
In order to set each equation equal to each other, we must have them both equal the same variable.
Rearrange the top equation to make it equal to y:
x - y = -4
Add 4 to both sides and add y to both sides:
x + 4 = y
Now, we can set both equations equal to each other:
x + 4 = 5(x + 1)² - 3
Begin solving by expanding the square binomial:
x + 4 = 5(x² + 2x + 1) - 3
Simplify:
x + 4 = 5x² + 10x + 5 - 3
x + 4 = 5x² + 10x + 2
Bring all terms to one side:
0 = 5x² + 9x - 2
Factor:
0 = (5x - 1)(x + 2)
Set the other factor equal to 0:
5x - 1 = 0
5x = 1
x = 1/5
Plug in this value of x into an original equation:
1/5 - y = -4
1/5 + 4 = y
1/5 + 20/5 = y
y = 21/5
Answer:
1. angle Y, angle XYZ, and angle ZYX
2. angle PQR, angle SQR, and angle PQS
Step-by-step explanation:
1. The 3 ways to name the given angle are:
✔️The use of an alphabet of the vertex: angle Y
✔️The use of the three alphabets can be named in two ways with the middle alphabet representing the vertex:
angle XYZ
angle ZYX
2. The three different angle in the diagram consist of two adjacent angles that share the same side: angle PQR and angle SQR,
and the bigger angle that sums up the two internal angles, which is angle PQS
