Algebra.Com's Answer #460114 by Cromlix(4381) You can put this solution on YOUR website! From the two triangles ADE and ABC \n" ); document.write( "Sides CB/ED = AB/ED \n" ); document.write( " 8/20 = 6/x \n" ); document.write( "Cross multiply \n" ); document.write( " 8x = 120 \n" ); document.write( " x = 120/8 \n" ); document.write( " x = 15 \n" ); document.write( "Length of AD is 15ft. \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
