If l parallel to m find y

y = 144

because l//m

=> y + x = 180°

but y = 4x (2 vertical angles) => x = y/4

with x = y/4

=> y + y/4 = 180°

⇔ 5y/4 = 180°

⇔ 5y = 180.4 = 720

⇔ y = 720/5 = 144

Step-by-step explanation:

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one
