Let \( ABC \) be a triangle (see the picture). Determine the angle \( \varphi \) between the height \( v_b \) and the angle bisector \( o_\alpha \). Give the angle rounded to minutes.
\( \varphi\doteq 71^{\circ}34' \)
\( \varphi\doteq 71^{\circ}33' \)
\( \varphi\doteq 71^{\circ}40' \)
\( \varphi\doteq 71^{\circ}38' \)
