АВ=ВС, т.к. треугольник равнобедренный, а АС - основание. ВК=2, АК=8, тогда, АВ=10. Центр вписанной окружности лежит в точке пересечения биссектрис треугольника, проведём биссектрису ВН: точка Н совпадёт с точкой касания окружности на стороне АС, т.к. в биссектриса, проведённая из угла В, является и высотой, и медианой, т.е. угол АНС = 90 градусов. АН=АК, т.к. отрезки касательных, проведённых из одной точки, равны, т.е. АН=8, тогда АС=16. В прямоугольном треугольнике АВН АВ=10, АН=8, тогда по теореме Пифагора ВН=6. Найдём площадь треугольника: 1/2 * АС * ВН = 1/2 * 16 * 6 = 42.
Abdilda Tazhibayev was born in 1909 in Akmeshit (now Kyzylorda). Medium
one hundred
The Kipchak tribe Tory clan is descended from Bessary's grandfather. [1] [2] His father, Tazhibai, died in 1915 and was left in the care of his mother, Aimankul.
