# A triangle has corners at points A, B, and C. Side AB has a length of #15 #. The distance between the intersection of point A's angle bisector with side BC and point B is #8 #. If side AC has a length of #15 #, what is the length of side BC?

Length of side

Let the point where the angle bisector intersects with side BC be D

It’s an isosceles triangle with sides AB & AC equal.

Hence BD = DC & BC = BD + DC = 2*BD

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
