A right-angled triangle \(ABC\) with the right angle at the vertex \(C\) is given in the picture. Calculate the height \(v_c\), if \(a=20\,\mathrm{cm}\) and \(\beta=50^{\circ}\).
\( 20\sin{50^{\circ}}\)
\( 20\cos{50^{\circ}}\)
\( 20 \mathop{\mathrm{tg}} {50^{\circ}}\)
\( \frac{20}{\sin{50^{\circ}}}\)
