Question

Am nevoie de ajutor la acest exercitiu

Answer 1

AOB=45
COD=30
BOD=75
FOD=60
GOF=72
GOE=102

Answer 2

Răspuns:

Explicație pas cu pas:

<AOB = <AOC/2 = 90°/2 = 45°

<COD = <COF/3 = (<AOF - <AOC)/3 = (180° - 90°)/3 = 90°/3 = 30°

<BOD = <BOC + <COD = 45° + 30° = 75°

<FOD = <FOE + <EOD = <COF/3 + <COF/3 = 30° + 30° = 60°

<GOF = <HOF/2 = (360° - <AOH - <AOF)/2 = (360° - 36° - 180°)/2 = 144°/2 = 72°

<GOE = <GOF + <FOE = 72° + 30° = 102°
