The rest of the letters, A, B, C, D, and E all have only 1 line of symmetry. Notice that the A has a vertical line of symmetry, while the B, C, D, and E have a horizontal line of symmetry.
Answer:
n=4
Step-by-step explanation:
Given equation: \[\frac{1}{n-4}-\frac{2}{n}=\frac{3}{4-n}\]
Simplifying the Left Hand Side of the equation by taking the LCM of the denominator terms:
\[\frac{n}{n*(n-4)}-\frac{2*(n-4)}{n*(n-4)}=\frac{3}{4-n}\]
=> \[\frac{n - 2*(n-4)}{n*(n-4)}=\frac{3}{4-n}\]
=> \[\frac{n - 2n + 8}{n*(n-4)}=\frac{3}{4-n}\]
=> \[\frac{8 - n}{n*(n-4)}=\frac{3}{4-n}\]
=> \[(8-n)*(4-n) =n*(n-4)*3\]
=> \[n-8 =3n\]
=> \[2n =8\]
=> n = 4

Your answer would be C: 44 degrees.
1. Find the value for the third angle.
We know that two of the angles are y, but we need to find the other angle in order to solve this problem. There is a line connecting off of the angle, so for a moment, lets ignore the triangle and just look at the line.
A line is 180 degrees. That means that if we subtract 88 from 180, we can get the value for the third angle. 180-88=92.
2. Find y.
The total value of all the angles of a triangle is 180 degrees. Lets first find the value of two of the y angles combined. 180-92=88
Since both of the remaining angles are y, that means that they are equal. This means that all we have to do now is divide 88 by 2 to get the value of y. 88/2=44
y=44 degrees
I'm really bad at explaining things, but I hope this helped!
