Биссектриса делит противоположную сторону пропорционально боковым сторонам треугольника. Составим систему уравнений:[latex] left { {{x+y=7} atop { frac{15}{x} = frac{20}{y} } ight. \ left { {{x=7-y} atop {20x=15y}} ight. \ 20(7-y)=15y \ 140-20y=15y \ 35y=140 \ y=4; x=3. [/latex]Ответ:Биссектриса делит противоположную сторону на отрезки 4 и 3 см.
