Find $x$ and $y$ in the following figure if $l\parallel m$.

Find $x$ and $y$  in the following figure if $l\parallel m$.

$$In given figure $l\parallel m$ and $n\parallel p$. Find $x, y$ and $z$.

In the give figure $l\parallel m$ and $n\parallel m$. Find $x,y$ and $z$.

$l\parallel m$ in the given the figure,and $n\parallel p$. Find $x,y$and $z$.

In the figure, $l\parallel m$. If the line $n$ bisects $\angle BPR$ then find $x$.

In the figure, the lines$l$and $m$ are parallel. Prove that  $x+y+z = 180°$.
