A triangle has corners at points A, B, and C. Side AB has a length of #16 #. 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 #27 #, what is the length of side BC?

Length of side BC = 21.5

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

#"using the "color(blue)"angle bisector theorem"#

#(AB)/(AC)=(BD)/(DC)#

#16 / 27 = 8 / (DC)#

#DC = (8*27) / 16 = 13.5#

#BC = BD+DC= 8+13.5 =21.5#
