The image shows parallel lines cut by transversal. The expressions represent unknown angle measurements what is the value of x

If the slope of one line equals the slope of another line then ? a) the two lines are intersecting lines b) the two lines are perpendicular lines c) the two lines are parallel lines d) the two lines always have very steep slopes

8000 + 8800 + 8000 + 8 million + 80 trillion + another a katrillion equals

Can someone me with this? i’m not sure what to put for my equations.
