Exercise 4.3

If the value of $\text{'}x\text{'}$ in the given figure is $k°$ then find $k$.

If $△\mathrm{MNO}\cong △\mathrm{DEF}, \angle \mathrm{M}=60°$ and $\angle \mathrm{E}=45°$ then if the value of $\angle \mathrm{O}=\mathrm{k}°$, then find the value of $k$.

In given figure $\mathrm{BD}=\mathrm{BC}$, if the value of $x=k°$ then find $k$.

In the given figure, if the value of $x=k°$ then find $k$.

In the given figure find the values of $x$ and $y$.

In $△\mathrm{DEF}, \angle \mathrm{F}=48°, \angle \mathrm{E}=68°$ and bisector of $\angle \mathrm{D}$ meets $\mathrm{FE}$ at $\mathrm{G}$. If $\angle \mathrm{FGD}=k°$, then find the value of $k$.

In the figure, if the value of $x=k°$, then find the value of $k$.

From the given figure find the value of $y$.
