Sifat-sifat sudut pada lingkaran:
[tex]\begin{aligned} \angle COD &= 2 \times \angle CAD \\&= 2 \times \left( \frac{\angle CBD + \angle CAD + \angle CED}{3} \right) \\&= 2 \times \left( \frac{120^{\circ}}{3} \right) \\&= 2 \times 40^{\circ} \\&= \boxed{\bold{\underline{80^{\circ}}}} \end{aligned}[/tex]
[tex]\boxed{\colorbox{ccddff}{Answered by Danial Alf'at | 22 - 05 - 2023}}[/tex]
<COD
= (2 . 120/3)°
= (2 . 120)/3)°
= (240/3)°
= 80°
