Б) Луч OM - биссектриса угла AOB, равного 60 градусов. Найдите углы AOP и BOQ, если угол POQ = 25 градусов угол MOP = 20 градусов и угол MOQ = 45 градусов
в) Луч OP делит угол AOB, равный 100 градусов, на два угла так, что 3 угла AOP = 7 углов BOP, луч OQ делит угол AOP на два угла так, что 3 угла AOQ = 4 угла POQ. Найдите угол между биссектрисами углов AOP и BOQ.
Г) Найдите угол AOM, если угол AOB = 120 градусов и угол AOM = 2 угла BOM
