EF and GH. those are the right answers
Answer:
109.5; B
Step-by-step explanation:
From your identity,
CosA = adjacent/ hypothenus
A represent an arbitrary angle between the sides in question.
In the question above, A=64
Hypothenus is the longest side and adjacent is the side just below the angle .
In the above case,
Hypothenus= X
adjacent =48
This means;
Cos64 = 48 /X
X = 48 / cos64; [ from cross multiplication and diving through by cos64]
X = 48 /0.4383 [ cos64 in radian = 0.4383]
= 109.51
= 109.5 to the nearest tenth.
Note( do your calculation of angle in radian or else, you won't get the answer)

<u><em>Find the range</em></u>

Before going to the question, let's review what range is:
Range is the difference between the greatest number and the least number in a data set. Finding range is pretty easy. All you need to do is find the greatest number and lowest number, and find the difference.
In this data set, you have the following numbers:
![3 | 4 | 11 | 6 | 5 | 7 | 6 | 2 | 4](https://tex.z-dn.net/?f=3%20%7C%204%20%7C%2011%20%7C%206%20%7C%205%20%7C%207%20%7C%206%20%7C%202%20%7C%204)
The greatest number is 11. The lowest number is 2. That means that the range is equal to:
![Range = 11-2](https://tex.z-dn.net/?f=Range%20%3D%2011-2)
Subtract:
![11-2=9](https://tex.z-dn.net/?f=11-2%3D9)
★ The range is 9 ; range = 9
