прямой угол = 90 градусов,значит
1+5=6 частей угол АОВ
90:6=15 градусов приходится на одну часть,а значит столько градусов угол СОВ
15*5=75 град угол АОС
===========================
90-46=44 градуса углы АОС и СОВ без разницы
44:2=22 град угол СОВ
22+46=68 град угол АОС
===========================
1+4=5 частей углы АОС и СОВ
90:5=18 град угол АОС
18*4=72 град угол СОВ
