Clockwise from top left, three lines are labeled $t$, $r$, and $s$. Line $t$ intersects both line $r$ and line $s$. At the intersection of line $t$ and $r$, the top-right angle is labeled $x^{\circ }$. At the intersection of line $t$ and $s$, the top-right angle is labeled $49^{\circ }$. Line $r$ is parallel to line $s$. What is the value of $x$?
