When a transversal cuts two parallel/non-parallel lines, then the number of pairs of interior alternate angles formed is

In the figure, $\mathrm{AB}\Vert \mathrm{CD}$. Transversal $\mathrm{PQ}$ intersects $\mathrm{AB}$ at $\mathrm{E}$ and $\mathrm{AC}$ at $\mathrm{F}$. If $\angle \mathrm{CFQ}=47°$, then the measures of $x$ and $y$, respectively are

In the given figure, $\mathrm{CE}\Vert \mathrm{BA}$. If $\angle \mathrm{BAC}=60°$ and $\angle \mathrm{ECD}=65°$, then what is the measure of $\angle ACB$?

In the given figure, $\mathrm{AB}\Vert \mathrm{ED}$ and $\mathrm{EF}\Vert \mathrm{CB}$. If $\angle \mathrm{EPC}=50°$, what is the measure of $\angle \mathrm{FED}+\angle \mathrm{ABC}$?
