Algebra.Com's Answer #510526 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! Since angles ABC and BCA are equal then sides AC and AB are equal \n" ); document.write( "(3x - 5)=(19 - x) \n" ); document.write( "4x=24 \n" ); document.write( "x=6 \n" ); document.write( "18-5=13 AB \n" ); document.write( "19-6=13 AC \n" ); document.write( "2*6=12 BC \n" ); document.write( "13+13+12=38 cm \n" ); document.write( " |
