The formula for the area of a parallelogram is b * h\r \n" ); document.write( "\n" ); document.write( "We are given an angle of 40 degrees, so we can construct a right triangle of degrees 40 90 50\r \n" ); document.write( "\n" ); document.write( "To find the height of the parallelogram, you can now use trigonometry; \r \n" ); document.write( "\n" ); document.write( "sin 40 degrees = opposite / hypotenuse\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "0.6428 = opposite / hypotenuse\r \n" ); document.write( "\n" ); document.write( "= 0.6428 * 8 = ~ 5.14\r \n" ); document.write( "\n" ); document.write( "This is the height. \n" ); document.write( "We can now use the formula b * h. which comes out to 5.14 * 14 = ~ 71.99\r \n" ); document.write( "\n" ); document.write( "Ancient Wizard Cleomenius \n" ); document.write( " |
