A triangle has corners at points A, B, and C. Side AB has a length of #18 #. The distance between the intersection of point A's angle bisector with side BC and point B is #7 #. If side AC has a length of #14 #, what is the length of side BC?

Answer 1

Length of side BC = 12.4444

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

#"using the "color(blue)"angle bisector theorem"#
#(AB)/(AC)=(BD)/(DC)#
#18 / 14 = 7 / (DC)#
#DC = (7*14) / 18 = 5.4444#
#BC = BD+DC= 7+5.444 =12.4444#

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.
