Two vertices of a right triangle have the coordinates (−2, 5) and (9, 5) .

-Dominant- [34]

Length = √(y2-y1)² + (x2-x1)²
l = √(5 - 5)² + (9 + 2)²
l = √0² + 11²
l = √121
l = 11

In short, Your Answer would be 11 units

Answer:

Set 2 has a wider spread and has range of 27

Explanation:

We are given the below two sets of data:

Set 1 Set 2

17 81

13 70

18 94

24 68

21 95

Now, let's find the range of Set 1:

$Range=Maximum-Minimum$

$=24-13$

$=11$

Now, let's find the range of Set 2:

$Range= Maximum -Minimum$

$=95-68$

$=27$

Since, the Set 2 has more range, therefore, Set 2 has a wider spread and a range of 27
