Lines & Angles Practice Test

In the diagram, lines $l$ and $m$ are parallel and are intersected by a transversal line $t$. If the measure of angle 1 is $70°$, what is the measure of angle 7?

Two lines intersect. One of the angles formed is $120^\circ$. Angle $x$ is adjacent to the $120^\circ$ angle, sharing a side with it, and the other sides form a straight line (a linear pair). What is the measure of angle $x$?
