Step-by-step explanation:
I don't understand. what are W, C, Y, Z ?
all I can do is solving the 4 systems of equations for x and y.
y = -2x - 3
y = 2x - 1
adding the equations
2y = 0 - 4 = -4
y = -2
-2 = 2x - 1
-1 = 2x
x = -1/2
y = x + 4
y = -x + 2
adding the equations
2y = 0 + 6 = 6
y = 3
3 = x + 4
x = -1
y = -2x + 3
y = x + 4
multiply second equation by 2, add the result to first
2y = 2x + 8
3y = 0 + 11 = 11
y = 11/3
11/3 = x + 4 = x + 12/3
x = -1/3
y = 2x - 1
y = -x + 2
multiply second equation by 2, add the result to first
2y = -2x + 4
3y = 0 + 3 = 3
y = 1
1 = -x + 2
-1 = -x
x = 1

Answer:
Angle 8 and angle 5 are the adjacent to each other
Hello!
Let's add the numbers up in each answer option and find the sums, then we can compare the sums to 13:
OPTION A:
7.7 + 5.6 = 13.3
The sum is 13.3, which is greater than 13.
OPTION B:
7.4 + 5.2 = 12.6
The sum is 12.6, which is less than 13.
OPTION C:
4.7 + 7.6 = 12.3
The sum is 12.3, which is less than 13.
OPTION D:
4.4 + 8.2 = 12.6
The sum is 12.6, which is less than 13.
So, the sum of Option A. is greater than 13!
