3p Gegeven is \(\triangle K\kern{-.8pt}L\kern{-.8pt}M\) met \(\angle K = 56\degree\) 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 ○ \(\angle M = 180\degree - 56\degree - 61\degree = 63\degree \text{.}\) 1p |

3p Gegeven is \(\triangle A\kern{-.8pt}B\kern{-.8pt}C\) met \(\angle C = 37\degree\) en \(\angle A = 33\degree \text{.}\) |
○ De som van de hoeken in \(\triangle A\kern{-.8pt}B\kern{-.8pt}C\) geeft \(\angle C + \angle A + \angle B = 180\degree \text{.}\) 1p ○ Dus \(\angle B = 180\degree - \angle C - \angle A \text{.}\) 1p ○ \(\angle B = 180\degree - 37\degree - 33\degree = 110\degree \text{.}\) 1p |
