→ jawaban :

  1. jika ∠aod +∠boc = 110° , maka besar ∠doc = 125°

→ penyelesaian :

jika ∠AOD + ∠BOC = 110° , maka besar ∠DOC adalah.....

jawab :

[tex] < doc = \frac{36° - ( < aod + < boc)}{2} [/tex]

[tex] < doc = \frac{360° - 110°}{2} [/tex]

[tex] < doc = \frac{250°}{2} [/tex]

[tex]{ \boxed{ \mathfrak{ = 125°}}}[/tex]

jadi besar <DOC adalah 125° ( C )

[tex]\rm\angle{AOD} + \angle{BOC} = 110^{\circ}[/tex]

karena besar sudut AOD dan BOC sama, maka kita dapat mengganti BOC dengan AOD.

[tex]\rm\angle{AOD} + \angle{AOD} = 110^{\circ}[/tex]

[tex]2\rm\angle{AOD} = 110^{\circ}[/tex]

[tex]\rm\angle{AOD} = \frac{110^{\circ}}{2}[/tex]

[tex]\rm\angle{AOD} = 55^{\circ}[/tex]

..

Menentukan besar [tex]\rm\angle{DOC} [/tex]

[tex]\rm\angle{DOC}+\angle{AOD} = 180^{\circ}[/tex]

[tex]\rm\angle{DOC}+55^{\circ}= 180^{\circ}[/tex]

[tex]\rm\angle{DOC}= 180^{\circ}-55^{\circ}[/tex]

[tex]\rm\angle{DOC}= 125^{\circ}[/tex]
