Triangle ABC is such that AB=8, AC=9, and BC=10 cm. The bisector of the interior angle BAC intersects BC in a point M. What is the length of the segment BM? Give you r answer as a common fraction in lowest term. These are tricky. I have worked on them for hours, and don't know what they are. If anyone wants interesting problems tell me. ( I kow the answers to those ) __________________ .
