Each triangle has angles whose sum is 180 degrees. \n" ); document.write( "If the vertex angle is 40 degrees, that leaves 140 degrees for the other two. \n" ); document.write( "If the triangle is isosceles the base angles are equal. \n" ); document.write( "So 2x=140 and each angle is 70 degrees. \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
