Let BM and CN be the external bisectors of the angels B=12 and C=132 of a special triangel ABC, each terminated at the opposition side. Without using trigonometric functions, compare the length of the angle bisectors.

As far as I understand this is asking either for the ratio of those bisectors OR asking the length of them separately. As the side lengths are not given I am assuming they are asking for the ratio.
