Answer:
Z =7
Step-by-step explanation:
The middle segment theorem of a triangle says that: A middle segment connecting two sides of a triangle is parallel to the third side and is half its length.
In this case, the middle segment connecting two sides of a triangle is Z.
This means that

Finally we have that:

The length of the middle segment is 7 units
Step-by-step explanation:
5x+3x=12+4
8x=16
x=16÷8
x=2
The answer is 4,560
4.56 X 1000
Y = -(1/2)x + 4
y + (1/2)x =4
(1/2)x + y = 4
Multiply both sides by 2
2*(1/2)x + 2*y = 2*4
x + 2y = 8
