Answer 3

as we can see these lines are parallel

Answer 4

and interior angles of parallel lines (lines cut by a transversal line ) are sum upto 180 degree alwys (rule of parallel line)

Answer 5

2x-y+60=180
2x-y=120
in other same rule will be applicable
2x+y+40=180
2x+y=140
now solve these 2 equations

Answer 6

i dont understand that cause i plug in the x and y of all 4 options and none of them add to 180

Answer 7

in the first equiation anyways i havnt tried the second

Answer 8

oh i wasnt adding the 40 or 60, thanks! :)
