Remember:
\n" ); document.write( "The sum of the three interior angles of any triangle equals 180.
\n" ); document.write( ".
\n" ); document.write( "The problem defined the three angles as:
\n" ); document.write( "(2x+4) angle 1
\n" ); document.write( "(2x-9) angle 2
\n" ); document.write( "x angle 3
\n" ); document.write( ".
\n" ); document.write( "Our equation is then
\n" ); document.write( "(2x+4) + (2x-9) + x = 180
\n" ); document.write( "Grouping like-terms:
\n" ); document.write( "(2x+2x+x) + (4-9) = 180
\n" ); document.write( "5x + (-5) = 180
\n" ); document.write( "5x - 5 = 180
\n" ); document.write( "5x = 185
\n" ); document.write( "x = 37 degrees (angle 3)
\n" ); document.write( ".
\n" ); document.write( "For angle 2, we said it was:
\n" ); document.write( "(2x-9)
\n" ); document.write( "substituting our value of x:
\n" ); document.write( "(2(37)-9)
\n" ); document.write( "74-9
\n" ); document.write( "65 degrees (angle 2)
\n" ); document.write( ".
\n" ); document.write( "For angle 1, we said it was:
\n" ); document.write( "(2x+4)
\n" ); document.write( "substituting our value of x:
\n" ); document.write( "(2(37)+4)
\n" ); document.write( "74 + 4
\n" ); document.write( "78 degrees (angle 1)
\n" ); document.write( " \n" ); document.write( "
\n" );
