Hey there!
The word reflected means when something is basically coping everything that you do. So, for example, when I look in a mirror, the mirror would reflect everything that I would do.
So, from looking at the graph above, as we should <em>remember </em>the
![\left[\begin{array}{ccc}\boxed{x-axis}\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%5Cboxed%7Bx-axis%7D%5Cend%7Barray%7D%5Cright%5D%20)
is the

that is
(horizontal) and the

is the

that is
(vertical).
So, from knowing this information of graphs, we now know that
![\left[\begin{array}{ccc}AB\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7DAB%5Cend%7Barray%7D%5Cright%5D%20)
are reflecting over the

which is the line that is
(horizontal).
Your correct answer would be
. . .

Hope this helps you!

Step-by-step explanation:
1) 7/23 + 11/23 + 9/23
7+11+9/23
27/23
= 1 4/23
2) 2 5/7 + 9 4/7
11 9/7
= 11.12
3) 9/20 + 3/5
9+12/20
21/20
= 1 1/20 or 1.05
The sum of their speeds is 380 miles per hour. The difference of their speeds is 30 miles per hour. Then the faster plane is traveling at
.. (380 +30)/2 = 205 miles per hour
The slower plane's speed is 30 miles per hour less, so it is traveling at
.. 205 mph -30 mph = 175 miles per hour
your answer is B= 12 your welcome :)
Therefore the probability that the angle measure are supplementary are:120,60
