Since the triangle is isosceles, the sides are the same length, x. The base is then x + 40.
\n" ); document.write( "So x + x + x + 40 = 370
\n" ); document.write( "3x + 40 = 370
\n" ); document.write( "3x = 330
\n" ); document.write( "x = 110
\n" ); document.write( "The lengths of the sides are 110 mm, 110 mm, and 150 mm.
\n" ); document.write( "
\n" );
