3p a Gegeven is \(\triangle ABC\) met \(\angle C=61\degree\) en \(\angle A=53\degree\text{.}\) |
a De som van de hoeken in \(\triangle ABC\) geeft \(\angle C+\angle A+\angle B=180\degree\text{.}\) 1p Dus \(\angle B=180\degree-\angle C-\angle A\text{.}\) 1p \(\angle B=180\degree-61\degree-53\degree=66\degree\text{.}\) 1p |

3p a Gegeven is \(\triangle KLM\) met \(\angle M=32\degree\) en \(\angle K=38\degree\text{.}\) |
a De som van de hoeken in \(\triangle KLM\) geeft \(\angle M+\angle K+\angle L=180\degree\text{.}\) 1p Dus \(\angle L=180\degree-\angle M-\angle K\text{.}\) 1p \(\angle L=180\degree-32\degree-38\degree=110\degree\text{.}\) 1p |
