A right-angled triangle \(ABC\) with the right angle at the vertex \(C\) is given in the picture. The length of the side \(c\) is \(5\,\mathrm{cm}\) and the measure of the angle \(\alpha\) is \(35^{\circ}\). What is the length of the side \(a\)?
\(5\sin{35^{\circ}}\,\mathrm{cm}\)
\(\frac{5}{\sin{35^{\circ}}}\,\mathrm{cm}\)
\(5\cos{35^{\circ}}\,\mathrm{cm}\)
\(\frac{5}{\cos{35^{\circ}}}\,\mathrm{cm}\)
