Answer:
x=6
angleC=70 degrees
Step-by-step explanation:
We can utilize the properties of a parallelogram to solve the problem.
First, we know that the two opposite parallel sides of a parallelogram are equal. This gives us the equation
2x+7=19
Solving, we get
2x=12
x=6
We also know that adjacent angles of a parallelogram always add up to 180 degrees. Thus, we get
110+angleC=180
Solving, we get
angleC=180-110
angleC=70 degrees

Answer:
graph c
Step-by-step explanation:
Given
| - 2x | = 4
The absolute value function always gives a positive result, however, the expression inside can be positive or negative , that is
- 2x = 4 or - (- 2x) = 4
Solving both
- 2x = 4 ( divide both sides by - 2 )
x = - 2
or
- (- 2x) = 4
2x = 4 ( divide both sides by 2 )
x = 2
The third graph indicates x = - 2 and x = 2 on the number line
