Algebra.Com's Answer #266438 by robertb(5830)![]() ![]() You can put this solution on YOUR website! Hmm. let's see: \n" ); document.write( "If x = unknown side, then the sides of the triangle are 4, 15, and x. By a combination of the use of the triangle inequality, \n" ); document.write( "4 + 15 > x, or 19 > x; \n" ); document.write( "4+x > 15, or x > 11; \n" ); document.write( "15 +x > 4, or x > -11. This last inequality doesn't give us any new information. But from the first two, we get \n" ); document.write( "19 > x > 11. There are 7 possibilities, looking at your list. Now you know... \n" ); document.write( " |
