Calculate the measures of interior angles \( \alpha \), \( \beta \) and \( \gamma \) of a triangle if \( \gamma=2\beta \) and \( \beta=3\alpha \).
\( \alpha=18^{\circ},\ \beta=54^{\circ},\ \gamma=108^{\circ} \)
\( \alpha=15^{\circ},\ \beta=45^{\circ},\ \gamma=90^{\circ} \)
\( \alpha=12^{\circ},\ \beta=54^{\circ},\ \gamma=111^{\circ} \)
\( \alpha=54^{\circ},\ \beta=18^{\circ},\ \gamma=108^{\circ} \)
