The sum of two consecutive interior angles formed by two parallel lines and a transversal is:

In a given figure, if $\mathrm{AB}\parallel \mathrm{CD}$, then measure of $\angle \mathrm{AED}$ is:

In the given figure, if $l\parallel m$, then values of $x$ and $y$ are

In a figure, if $\mathrm{OP}\parallel \mathrm{RS}$, $\angle \mathrm{QRS}=130°$ and $\angle \mathrm{OPQ}=110°$, then $\angle \mathrm{PQR}$ is equal to:

For what value of $x$ will lines $p$ and $q$ be parallel to each other?

In the following figure, if $\mathrm{AB}\parallel \mathrm{CD}\parallel \mathrm{EF}$, then $\mathrm{PQ}\parallel \mathrm{RS}, \angle \mathrm{CQP}=60°$ and $\mathrm{RQD}=25°,$ then reflex $\angle \mathrm{QRS}$ is equal: 

In the adjoining figure, the value of $x$ is:
