In the geometric plane, line $k$ is parallel to line $m$. A transversal line $t$ intersects line $k$ at point $P$ and line $m$ at point $Q$. Ray $PR$ extends along line $k$ to the right of $P$, and ray $QS$ extends along line $m$ to the right of $Q$. The measure of interior angle $\angle RPQ$ is represented by $(3x + 20)^\circ$ and the measure of interior angle $\angle PQS$ is represented by $(2x + 10)^\circ$. Which of the following statements must be true? Select all such statements.
