B3. In triangle ABC, the angle $\alpha=58^{\circ}$ and the angle $\beta=84^{\circ}$. What is the measure of angle $x$ between the angle bisector of $\gamma$ and the altitude to side $c$?
B3. The angle $x$ can be calculated in two ways, namely $x=\frac{\gamma}{2}-$ $\left(90^{\circ}-\beta\right)=19^{\circ}-6^{\circ}=13^{\circ}$ or $x=90^{\circ}-\alpha-\frac{\gamma}{2}=32^{\circ}-19^{\circ}=$ $13^{\circ}$.
