можно через переменные решитьпусть < оав - х, а < ова - у

рассмотрим δ аовх + у + 98 = 180 (по теореме)

х + у = 82

2) рассмотрим δ авс

т.к аn и вl -биссектрисы,то < а = < оав * 2 = 2х и < в = 2 * ова = 2 у

< с примем за z

2 х + 2 у + z = 180 2 (x + y) + z = 180

2 * 82 + z = 180

z + 164 = 180

z = 180 - 164 = 16

внешний < при < с = 180 - 16 = 164

ответ : 164
