You can put this solution on YOUR website!
if they're collinear and X is between Y and Z, then the order of the points would be YXZ or ZXY depending on how you want to set them up.
\n" ); document.write( "i set them up as YXZ.
\n" ); document.write( "you're given:
\n" ); document.write( "XY = 14.8
\n" ); document.write( "YZ = 18.2
\n" ); document.write( "since YZ is the whole line and X is in between then YX + XZ must equal to YZ because the sum of the parts equals the whole.
\n" ); document.write( "substituting known values in that equation we get
\n" ); document.write( "YX + XZ = YZ
\n" ); document.write( "14.8 + XZ = 18.2
\n" ); document.write( "XZ = 18.2 - 14.8
\n" ); document.write( "XZ = 3.4
\n" ); document.write( "going back to the original equation and substituting for known values, we get
\n" ); document.write( "YX + XZ = YZ
\n" ); document.write( "14.8 + 3.4 = 18.2
\n" ); document.write( "18.2 = 18.2
\n" ); document.write( "XZ = 3.4 is correct.
\n" ); document.write( "please note YX and XY are the same line.\r
