$A$ straight angle has measure......... (in $^{\circ}$)

In the given figure,if $PQ || RS$,$RS || MN$ and $y: z = 7: 11$,then find $x$. (in $^o$)

State whether each of the following statements is true or false:
$(1)$ If a transversal intersects two parallel lines,then the interior angles on the same side of the transversal are equal.
$(2)$ The maximum number of acute angles in any triangle is two.

The supplementary angle of the complementary angle of an angle having measure $32^{\circ}$ has measure.......... (in $^{\circ}$)

Find the measure of the supplementary angle of an angle of $52^{\circ}$. (in $^{\circ}$)

If in the figure,bisectors $AP$ and $BQ$ of the alternate interior angles are parallel,then show that $l \parallel m$.
