Since this polygon has four angles it's a rectangle. We know that the sum of interior angles of the rectangle is 360 degree.We write the equation:\r

\n" ); document.write( "\n" ); document.write( "Answer:The angles of the rectangle are:5*12+30=90; 10*12-10=110; 8*12-1=95 and
\n" ); document.write( " 6*12-7=65 degree.
