First angle = x \n" ); document.write( "Second angle = 2x \n" ); document.write( "Third angle = x + 40 \n" ); document.write( "Total angles in a triangle = 180 degrees \n" ); document.write( "x + 2x + x + 40 = 180 \n" ); document.write( "Collect like terms \n" ); document.write( "4x + 40 = 180 \n" ); document.write( "4x = 180 - 40 \n" ); document.write( "4x = 140 \n" ); document.write( "x = 35 degrees \n" ); document.write( "First angle = 35 degrees \n" ); document.write( "Second angle = 70 degrees \n" ); document.write( "Third angle = 75 degrees \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
