Can anyone find, the length of line segment MN.
It would be XY+AB/2. I know how to do it but im still having trouble. Thanks

Answer 1

got pic? since we are not seeing what MN stand for, or XY or AB

Answer 2

actually, lemme hmm nevermind that, since I'm blind, you do have it...my bad =|

Answer 3

Answer 4

ok.... so hmmm

notice the "tickmarks", meaning, those sides, AM, MX, XC as well BN, NY, YC, are all equal in length, let us.... call the length.. hmmm say hmmmm K

also bear in mind, that the lines MN as well as the XY, makes similar triangles with the bigger one containing all

so


so.. using proportions then, one could say that \(\bf \cfrac{48}{7x+4}=\cfrac{3\cancel{k}}{2\cancel{k}}\implies \cfrac{48}{7x+4}=\cfrac{3}{2}\)

see that?
