\"The second angle of a triangle is twice as large as the first angle. The third angle is 12degrees more than four times the first angle. How large are the angles?\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = first angle
\n" ); document.write( "2x = second angle {second angle is twice as large as first}
\n" ); document.write( "4x + 12 = third angle {twelve more than four times the first}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "All angles of a triangle add up to 180.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + 2x + 4x + 12 = 180 {added up all angles and set equal to 180}
\n" ); document.write( "7x + 12 = 180 {combined like terms}
\n" ); document.write( "7x = 168 {subtracted 12 from both sides}
\n" ); document.write( "x = 24 {divided both sides by 7}
\n" ); document.write( "2x = 48 {substituted 24, in for x, into 2x}
\n" ); document.write( "4x + 12 = 108 {substituted 24, in for x, into 4x + 12}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "24, 48, and 108 are the angles\r
