3p Gegeven is \(\triangle K\kern{-.8pt}L\kern{-.8pt}M\) met \(\angle K=69\degree\) en \(\angle L=61\degree\text{.}\) |
○ De som van de hoeken in \(\triangle K\kern{-.8pt}L\kern{-.8pt}M\) geeft \(\angle K+\angle L+\angle M=180\degree\text{.}\) 1p ○ Dus \(\angle M=180\degree-\angle K-\angle L\text{.}\) 1p ○ \(\angle M=180\degree-69\degree-61\degree=50\degree\text{.}\) 1p |

3p Gegeven is \(\triangle P\kern{-.8pt}Q\kern{-.8pt}R\) met \(\angle Q=38\degree\) en \(\angle R=37\degree\text{.}\) |
○ 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 ○ \(\angle P=180\degree-38\degree-37\degree=105\degree\text{.}\) 1p |
