3p a Gegeven is \(\triangle PQR\) met \(\angle P=73\degree\) en \(\angle Q=68\degree\text{.}\) |
a De som van de hoeken in \(\triangle PQR\) geeft \(\angle P+\angle Q+\angle R=180\degree\text{.}\) 1p Dus \(\angle R=180\degree-\angle P-\angle Q\text{.}\) 1p \(\angle R=180\degree-73\degree-68\degree=39\degree\text{.}\) 1p |

3p a Gegeven is \(\triangle ABC\) met \(\angle C=36\degree\) en \(\angle A=33\degree\text{.}\) |
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 \(\angle B=180\degree-36\degree-33\degree=111\degree\text{.}\) 1p |
