A leather coin purse has the shape of a triangle. Two sides are equal in length and the third side is 3 centimeters shorter than one-half times the length of the equal sides. The perimeter is 28.5 centimeters. Find the lengths of the sides.
\n" ); document.write( "...
\n" ); document.write( "let the equal sides be x
\n" ); document.write( "third side = x/2 -3 cm
\n" ); document.write( "x+x + 0.5x-3=28.5
\n" ); document.write( "2.5x=28.5+3
\n" ); document.write( "2.5x=31.5
\n" ); document.write( "/2.5
\n" ); document.write( "x= 12.6 equal side
\n" ); document.write( "third side = 0.5x-3
\n" ); document.write( "0.5 * 12.6 -3
\n" ); document.write( "=3.3 third side
