Since the angles two and four are vertical they have to equal each other so you put that in an equation and solve for x:
7x+7=140
-7 -7
7x=133 divide both sides by 7
x=19
Since angles 3 and 4 have to equal 180 to make a straight line they have to add together and equal 180 and solve for y:
5y+140=180
-140 -140
5y=40 divide both sides by 5
y=8
So your answer is x=19 and y=8

$\bf \sqrt{\cfrac{100}{144}}~~
\begin{cases}
100=10\cdot 10\\
\qquad 10^2\\
144=12\cdot 12\\
\qquad 12^2
\end{cases}\implies \sqrt{\cfrac{10^2}{12^2}}\implies \cfrac{10}{12}\implies \stackrel{simplified}{\cfrac{5}{6}}$

Answer:

D) The data are skewed and there are outliers.

Step-by-step explanation:

They don’t have the same mean (8) and median (9).

The peak is not equal to the median.

The data is not symmetrical.

That just leaves D, which is correct. The data is skewed to the right and has outliers at 0.
