Given:
The figure of a trapezium.
To find:
The measures of missing angle 
.
Solution:
In the given figure 
.
If a transversal line intersect the two parallel lines, then the same sides interior angles are supplementary angles.
(Supplementary angles)
Similarly,
(Supplementary angles)
Therefore, and .
Answer:
When x = 12, y = 4, and z = 2, 8x + 2yz = 112.
Step-by-step explanation:
8x + 2yz
Substitute variables given:
x = 12
y = 4
z = 2
8(12) + 2(4)(2)
Multiply 8 and 12.
96 + 2(4)(2)
Multiply 2 and 4.
96 + 8(2)
Multiply 8 and 2.
96 + 16
Add 96 and 16.
112.
The second picture should be the correct graph or the one which has its blue on the bottom side.
