Answer 2

Răspuns:

Explicație pas cu pas:

OE=bisect AOC atunci AOE=EOC=a

OF=bisect BOD atunci DOF=FOB=b

AOB=180 de grade

a+a+COD+b+b=180 de grade

2a+2b+COD=180 grade

2 x (a +b)+COD=180 grade

a+145 grade+b=180 grade

a+b=180 grade-145 grade=35 grade

2 x 35 grade +COD=180 grade

70 grade +COD=180 grade

COD=110 grade
