Answer:
<u>Rotation, then Translation, then Reflection</u>
Step-by-step explanation:
See the attached figure.
as shown in the figure
Triangle ABC is first rotated about point C to form triangle A'B'C. (<u>rotation</u>)
Triangle A'B'C is then shifted down to form triangle A''B''C'. (<u>translation</u>)
Triangle A''B''C' is reflected across A''B'' to form triangle A''B''C'' (<u>reflection</u>)
So, the answer is second option <u>rotation, then translation, then reflection</u>

Answer:
Option A) 15.5 is correct
The new median for the new data set is 15.5
Step-by-step explanation:
Given data set is 8,21,17,13
To find the median :
First order the given set of data into least to greatest
The ordered set is 8,13,17,21
Since the given set of data is even
We can take midvalues of data in the set
Median is the mean of two middle values in the data set
Therefore Median=15 ( given )
Given that if 17 is changed to 18 then the given set of data 8,21,17,13 is changed into new set 8,21,18,13
To find the median :
First order the new set of data into least to greatest
The ordered set is 8,13,18,21
Since the given set of data is even
We can take two midvalues of new data in the set
Median is the mean of two middle values in the data set
Therefore New Median=15.5
Therefore option A) 15.5 is correct
The new median for the new data set is 15.5
Answer: 8.6 from Ranger Christ and 6.8 from Ranger Rick
Step-by-step explanation:
The sides of triangle with A point as Ranger christ, B point as Ranger rick and C point at which two fires intersect.
This can be better understood by using law of sines
=
=
Solving we get
a= 8.6
and b= 6.8
