Algebra.Com's Answer #65535 by checkley75(3666) ![]() You can put this solution on YOUR website! WHAT YOU HAVE ARE 2 RIGHT TRIANGLES WITH ONE SIDE 5 MILES THE OTHER SIDE 10 MILES. NOW WE NEED TO FIND THE THIRD SIDE (HYPOTENUSE) THUS: \n" ); document.write( "5^2+10^2=H^2 \n" ); document.write( "25+100=H^2 \n" ); document.write( "125=H^2 \n" ); document.write( "H=SQRT125 \n" ); document.write( "H=11.28 MILES. NOW WE HAVE TO DOUBLE THIS VALUE SO 2*11.28=22.36 MILES APART ARE THESE 2 TRAINS. \n" ); document.write( " |
