Ответ:

угол CPB=104°; угол DPC=76°

Объяснение:

номер 1: 1)Найдём угол CPB

Угол :BPK+угол CPB = 180° (сумма смежных углов)

Угол BPK = 76° (по условию)

Тогда угол CPB = 180°-76°=104°

2)Найдём угол DPC

это можно сделать тремя способами

1.Угол DPC=углу BPK (как вертикальные)

значит угол DPC = 76°

2.Угол DPC + угол CPB = 180° (смежные углы)

значит угол DPC = 180° - 104° (угол CPB) = 76°

3.Угол BPK + угол KPD = 180° (сумма смежных углов)

тогда угол KPD = 180° - 76° (угол BPK) = 104°

Угол KPD + угол DPC = 180° (сумма смежных углов)

значит угол DPC = 180° - 104° (угол KPD) = 76°
