Algebra.Com's Answer #133537 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! In triangle ABC, line CD is both the median and the altitude to side AB. If AB=5x+3, AC=2x+8, and BC=3x+5, what is the perimeter of triangle ABC? \n" ); document.write( ": \n" ); document.write( "If the median is the same as the altitude, this triangle has two equal sides, \n" ); document.write( "namely, AC and BC, therefore: \n" ); document.write( "2x + 8 = 3x + 5 \n" ); document.write( "8 - 5 = 3x - 2x \n" ); document.write( "x = 3 \n" ); document.write( ": \n" ); document.write( "AB: 5(3) + 3 = 18 \n" ); document.write( "AC: 2(3) + 8 = 14 \n" ); document.write( "BC: 3(3) + 5 = 14 \n" ); document.write( "------------------ \n" ); document.write( "the perimeter: 46 \n" ); document.write( " |
