3p a Gegeven is \(\triangle ABC\) met \(\angle A=55\degree\) en \(\angle B=68\degree\text{.}\) |
a De som van de hoeken in \(\triangle ABC\) geeft \(\angle A+\angle B+\angle C=180\degree\text{.}\) 1p Dus \(\angle C=180\degree-\angle A-\angle B\text{.}\) 1p \(\angle C=180\degree-55\degree-68\degree=57\degree\text{.}\) 1p |
