You can put this solution on YOUR website!
x, y, and z = the measures of the three angle, in degrees:
\n" ); document.write( "---
\n" ); document.write( "3/9 = x/y
\n" ); document.write( "9/12 = y/z
\n" ); document.write( "x + y + z = 180
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "9x - 3y = 0
\n" ); document.write( "12y - 9z = 0
\n" ); document.write( "x + y + z = 180
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
