Garrett Detone: If you consider the triangle ABC then :cos B = BC / ABcos B = 12 / 14Now when you look at the triangle BCD you'll see that cos B = BD / BC.seeing as the angle B is the same in both triangles, then :BD / BC = cos BBD / 12 = 12 / 14BD = (12 x 12) / 14 = 144 / 14 = 72 / 7the answer is B...Show more
