Interior angles of a triangle \( ABC \) are in the ratio \( \alpha:\beta:\gamma=3:5:7 \). Calculate the measures of these angles.
\( \alpha=36^{\circ},\ \beta=60^{\circ},\ \gamma=84^{\circ} \)
\( \alpha=30^{\circ},\ \beta=50^{\circ},\ \gamma=70^{\circ} \)
\( \alpha=16.5^{\circ},\ \beta=30^{\circ},\ \gamma=133.5^{\circ} \)
\( \alpha=84^{\circ},\ \beta=60^{\circ},\ \gamma=36^{\circ} \)
