Interior angles of a triangle \( ABC \) are in the ratio \( \alpha:\beta:\gamma=2:4:6 \). Calculate the measures of these angles.
\( \alpha=30^{\circ},\ \beta=60^{\circ},\ \gamma=90^{\circ} \)
\( \alpha=20^{\circ},\ \beta=40^{\circ},\ \gamma=60^{\circ} \)
\( \alpha=15^{\circ},\ \beta=30^{\circ},\ \gamma=135^{\circ} \)
\( \alpha=90^{\circ},\ \beta=60^{\circ},\ \gamma=30^{\circ} \)
