The sum of all the angles of a quadrilateral is 360.
\n" ); document.write( "Therefore the two unknown angles sum to 360 - 45 - 85 = 230 degrees.
\n" ); document.write( "If the two angles are in the ratio 15 to 8, we can say they are 15x to 8x.
\n" ); document.write( "Thus 15x + 8x = 230,
\n" ); document.write( "23x = 230
\n" ); document.write( "x = 10
\n" ); document.write( "and the angles are
\n" ); document.write( "150 and 80 degrees.
\n" ); document.write( "
