\(\beta=180^\circ-90^\circ-35^\circ=55^\circ\)
Sinussatz: \(\frac{\sin(\alpha)}{a}=\frac{\sin(\beta)}{b}\Rightarrow a=\frac{\sin(\alpha)}{\sin(\beta)}\cdot b=\frac{\sin(35^\circ)}{\sin(55^\circ)}\cdot 14,5cm=10,2cm\)
Satz des Pythagoras: \(c^2=a^2+b^2\Rightarrow c=\sqrt{a^2+b^2}=\sqrt{(10,2cm)^2+(14,5cm)^2}=17,7cm\)
