thanks!

Step-by-step explanation:

if the two are two be equal, we have to find the value of x assuming they are equal.

refer the attachment to see the transversal. (the purple dotted lines are the same lines produced)

in this transversal, x+ECD=180 deg

o find ECD, we use:

70 = ECD + 30

40 = ECD

x+ECD=180 deg

x+40 = 180 deg

x = 140 deg
