Algebra.Com's Answer #42008 by uma(370)![]() ![]() ![]() You can put this solution on YOUR website! I think the figure is a rectangle. \n" ); document.write( "Length = 19.2 cm \n" ); document.write( "width = 12.4 cm \n" ); document.write( "With the diagonal, the figure becomes a right triangle with the length as its base and the width as its height. \n" ); document.write( " Let the angle between the diagonal and the shorter side be x \n" ); document.write( "Then tanx = 19.2/12.4 \n" ); document.write( " = 1.55\r \n" ); document.write( "\n" ); document.write( "==> x = tan^(-1) (1.55) \n" ); document.write( " = 57 degrees.(approx)\r \n" ); document.write( "\n" ); document.write( "The angle between the diagonal and the shorter side = 57 degrees.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Good Luck!!! \n" ); document.write( " |
