Answer:

В треугольнике ABC, AB = 15, BC = 7, CA = 9. Точка D лежит на прямой BC причем BD : DC = 5 : 7. ... ADC и ADB касаются стороны AD в точках E и F. Найдите длину отрезка EF.

Let AD and DB be 5x and 7x

As D lies on AB

AD + DB = AB

5x + 7x = 12

12x = 12

x = 1

therefore, AD = 5 and DB = 7
