a flag in the shape of an isosceles triangle has a base that is 3.5 inches shorter than either of the equal sides. If the perimeter of the triangle is 49 inches, what is the length of the equal sides?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let one of the 2 equal sides be A
\n" ); document.write( "the base is 3.5 inches shorter than either of the equal sides
\n" ); document.write( "the base is A - 3.5
\n" ); document.write( "A + A + (A - 3.5) = 49 inches = Perimeter P
\n" ); document.write( "3A - 3.5 = 49
\n" ); document.write( "3A = 52.5
\n" ); document.write( "A = 17.5 inches --> length of one of the 2 equal sides
\n" ); document.write( "base then is 17.5 - 3.5 = 14 inches
\n" ); document.write( "
\n" ); document.write( "
\n" );
