[tex]A=140^\circ, C=10^\circ, c=7^\circ[/tex]
[tex]B = 180^\circ - A - C = 30^\circ[/tex]
Law of Sines:
[tex] \dfrac{a}{\sin A} = \dfrac{b}{\sin B} = \dfrac{c}{\sin C} [/tex]
[tex] a= c \cdot \dfrac{\sin A}{\sin C} = 7 \cdot \dfrac{\sin 140}{\sin 10} \approx 25.9[/tex]
[tex]b = c \cdot \dfrac{\sin B}{\sin C} = 7 \cdot \dfrac{\sin 30}{\sin 10} \approx 20.2[/tex]
