\[Дано:\]
\[\mathrm{\Delta}ABC;\]
\[AB = 12\ см;\]
\[BC = 10\ см;\]
\[\sin{\angle A} = 0,2.\]
\[Найти:\]
\[\sin{\angle C}.\]
\[Решение.\]
\[\frac{\text{AB}}{\sin{\angle C}} = \frac{\text{BC}}{\sin{\angle A}};\]
\[\sin{\angle C} = \frac{AB \bullet \sin{\angle A}}{\text{BC}};\]
\[\sin{\angle C} = \frac{12 \bullet 0,2}{10} = 0,24.\]
\[Ответ:\ \ 0,24.\]
