Step-by-step explanation:
We know that the range to a data set is the difference between the maximum data value and the minimum data value .
The given data set : 29, 30, 28, 32, 28, 31, 27
Maximum value = 32
Minimum value = 27
Then , the range the given data set would be :-
\begin{gathered}\text{Range = Maximum-Minimum}\\\\\Rightarrow\text{Range}=32-27=5\end{gathered}Range = Maximum-Minimum⇒Range=32−27=5
Hence, the range of her distances = 5
ANSWER
x=27
EXPLANATION
The two triangles are similar so the corresponding sides are equal.


Cross multiply to get;

Expand:
65x=39x+702
Group similar terms:
65x-39x=702
Simplify
26x=102
Divide both sides by 26,
x=702/26
x=27
