What is the value of x? hurry pls

the correct answer is third option 20

step-by-step explanation:

from the figure we can see a parallelogram pqrs

to find the value of x

pqrs is a parallelogram , so the adjacent angles are supplementary.

20 + 2x   + 6x = 180

20 + 8x = 180

8x = 180 - 20

8x = 160

x = 160/8 = 20

therefore the value of x = 20

the correct answer is third option, 20

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
