3p Gegeven is \(\triangle A\kern{-.8pt}B\kern{-.8pt}C\) met \(\angle B=63\degree\) en \(\angle C=68\degree\text{.}\) |
○ De som van de hoeken in \(\triangle A\kern{-.8pt}B\kern{-.8pt}C\) geeft \(\angle B+\angle C+\angle A=180\degree\text{.}\) 1p ○ Dus \(\angle A=180\degree-\angle B-\angle C\text{.}\) 1p ○ \(\angle A=180\degree-63\degree-68\degree=49\degree\text{.}\) 1p |

3p Gegeven is \(\triangle P\kern{-.8pt}Q\kern{-.8pt}R\) met \(\angle Q=32\degree\) en \(\angle R=34\degree\text{.}\) |
○ De som van de hoeken in \(\triangle P\kern{-.8pt}Q\kern{-.8pt}R\) geeft \(\angle Q+\angle R+\angle P=180\degree\text{.}\) 1p ○ Dus \(\angle P=180\degree-\angle Q-\angle R\text{.}\) 1p ○ \(\angle P=180\degree-32\degree-34\degree=114\degree\text{.}\) 1p |
