1. If the angle of a triangle are in the ratio if 5:3:7,then what triangle is it
\n" ); document.write( "----
\n" ); document.write( "Solve for \"x\":
\n" ); document.write( "5x + 3x + 7x = 180
\n" ); document.write( "15x = 180
\n" ); document.write( "x = 12
\n" ); document.write( "---
\n" ); document.write( "3x = 36 degrees
\n" ); document.write( "5x = 60 degrees
\n" ); document.write( "7x = 84 degrees
\n" ); document.write( "----
\n" ); document.write( "Type of triangle: scalene
\n" ); document.write( "==================================\r
\n" ); document.write( "\n" ); document.write( "2. The angle which is twice its supplement is ?
\n" ); document.write( "Let the angle be \"x\".
\n" ); document.write( "Its supplement is \"180-x\".
\n" ); document.write( "---
\n" ); document.write( "Equation:
\n" ); document.write( "x = 2(180-x)
\n" ); document.write( "x = 360-2x
\n" ); document.write( "3x = 360
\n" ); document.write( "x = 120 degrees
\n" ); document.write( "-------
