Question

In the figure above, if ABCD is a parallelogram,
what is the value of 2y – x?​

Answer 1

Answer:

Step-by-step explanation:

x+y=150(corresponding angles)

x=150-y

x-y+x+y=180(sum of adjuscent angles)

150-y-y+150-y+y=180

300-2y=180

-2y=-120

y=60

x=150-y

 =150-60

 =90

2y-x= 2*60-90

       =120-90

        =30
