False, both lines are oblique (diagonal) so they meet at some point on a graph. They can only have no solutions if the lines are parallel/have the same slope.
It is A. ....... i wish you had a whole chart
Sum of all adjacent angles is 180°.
3x + 12 + x = 180
4x + 12 = 180
4x = 168
x = 42°

Answer: x = 42°

There is no way to tell because there is no value for x and y. However just looking at the picture, I’m guessing m is around 45 degrees.
