The answer is 16 because 16+2=18-4=14
Answer:

Step-by-step explanation:
we know that

Remember the identity

step 1
Find the value of 
we have that
The angle alpha lie on the III Quadrant
so
The values of sine and cosine are negative

Find the value of sine

substitute




step 2
Find the value of 
we have that
The angle beta lie on the IV Quadrant
so
The value of the cosine is positive and the value of the sine is negative

Find the value of cosine

substitute




step 3
Find cos (α + β)

we have




substitute



Answer:
Step-by-step explanation:
5x = 2x + 9
3x = 9
x = 3
AB= 5(3)= 15
BC= 2(5) + 9= 10 + 9 = 19
AC= 15 + 19 = 34
Though the box plot is not given, the truth about the data set represented by the box plot is <u>removing</u> the outliers would not affect the median.
<h3>What is a box plot?</h3>
A box plot gives a graphical (rectangular) representation of statistical data based on the following five values: minimum, first quartile, median, third quartile, and maximum.
Essentially, a box plot has the following five data descriptions:
- The leftmost whisker, showing the minimum value.
- The rightmost whisker, showing the maximum value.
- The leftmost line, showing the first quartile.
- The middle line, showing the median or the second quartile.
- The last line shows the third quartile.
Thus, the truth about the data set represented by the box plot is <u>removing</u> the outliers would not affect the median.
