Периметр треугольника равен 166 см.Одна из его сторон в 5 раз больше второй,которая на 68 см меньше третьей.Вычислите длины сторон треугольника
решение
примем
а, см - 1-я сторона треугольника
в, см - 2-я сторона треугольника
с, см - 3-я сторона треугольника
тогда
Р=а+в+с
а=5*в
в=с-68
а=5*(с-68)=5*с-340
тогда
(5*с-340)+(с-68)+с=166
5*с-340+с-68+с=166
7*с=166+340+68
с=574/7
с=82
в=82-68=14
а=5*14=70
проверим
70+14+82=166
166=166
70, см - 1-я сторона треугольника
14, см - 2-я сторона треугольника
82, см - 3-я сторона треугольника
