A quad's angles total 360.
\n" ); document.write( "a quad has 4 angles. Two sets of two which are equal\r
\n" ); document.write( "\n" ); document.write( "so we have 2*3x+2*(4x+12)=360
\n" ); document.write( "6x+8x+24=360
\n" ); document.write( "14x=360-24
\n" ); document.write( "14x=336
\n" ); document.write( "7x=118
\n" ); document.write( "x=24
\n" ); document.write( "one angle is 3x=3*24=72
\n" ); document.write( "the other is 4x+12=4*24+12=96+12=108
\n" ); document.write( "so we have 72, 108, 72, 108\r
\n" ); document.write( "
