Best ResponseYou've already chosen the best response.1you essentially use the side splitter theorem http://www.cliffsnotes.com/study_guide/ProportionalPartsofTriangles.topicArticleId18851,articleId18813.html and that allows you to say "If a line is parallel to one side of a triangle and intersects the other two sides, it divides those sides proportionally. " what this means is that you can effectively say that AD/AB = JM/LM (4AB)/AB = JM/7 4 = JM/7 4*7 = JM 28 = JM JM = 28 So JM is 28 units

Best ResponseYou've already chosen the best response.1oh wait, it should be AD/AB = JM/LM (3AB)/AB = JM/7 3 = JM/7 3*7 = JM 21 = JM JM = 21 So JM is 21 units
