Answer:
1/4 of the answer
Step-by-step explanation:
The total number of degrees in would be 720. By subtracting all other angles you will find x.
720-129-105-135-130-95=126
X=126

Is AB and CD parallel?
First, we need to calculate the slope (m) of AB and CD

For AB:


So:





For CD:


So:




For Lines to be parallel, the slope must be equal:
i.e. 
This condition is not true because:

For Lines to be perpendicular, the slope must be:

This implies:



<em>Hence, the lines are perpendicular</em>
