Let \( ABC \) be a triangle (see the picture). Determine the angle \( \varphi \) between the height \( v_c \) and the median \( t_c \). Give the angle rounded to minutes.
\( \varphi\doteq 21^{\circ}48' \)
\( \varphi\doteq 21^{\circ}24' \)
\( \varphi\doteq 21^{\circ}36' \)
\( \varphi\doteq 21^{\circ}52' \)
