Zimed Posted December 10, 2006 Share Posted December 10, 2006 I need help with this problem, it is very confusing to me, can anyone help, and explain how to? Thanks. http://img186.imageshack.us/img186/3112/gfgfgyc6.jpg And another problem, very related to this one is this. http://img241.imageshack.us/img241/7311/anotherproblemol7.jpg Link to comment Share on other sites More sharing options...
EvoN1020v Posted December 10, 2006 Share Posted December 10, 2006 Median in another word, is midpoint. In the first diagram, the line BD touches the midpoint of line AC. Link to comment Share on other sites More sharing options...
Zimed Posted December 10, 2006 Author Share Posted December 10, 2006 So, to I set the two values, on line AC equal to one another, to solve to get the value of X? Or what do I do? Thank you for clarifying. Link to comment Share on other sites More sharing options...
the tree Posted December 10, 2006 Share Posted December 10, 2006 By Evo's definition, the two expressions are equal to each other, yes. Honestly, I'm a bit confused by it, I can't work out what on earth (15x+42) is pointing to. Link to comment Share on other sites More sharing options...
Zimed Posted December 10, 2006 Author Share Posted December 10, 2006 It is pointing towards...I believe the angle right above line AC...but this is a guess as well, as it is quite unclear. Link to comment Share on other sites More sharing options...
EvoN1020v Posted December 10, 2006 Share Posted December 10, 2006 You perhaps can assume that [math]15x+42[/math] is the equation for the length of line BD. Link to comment Share on other sites More sharing options...
babu_ipsita Posted March 27, 2007 Share Posted March 27, 2007 10x-7=5x+3 or, x=2 no other information is needed. Link to comment Share on other sites More sharing options...
