Algebra.Com's Answer #332946 by cleomenius(959) You can put this solution on YOUR website! For a, first I converted the angle to degrees. \n" ); document.write( "First convert the minutes, 4, to a decimal part. \n" ); document.write( "We know that 60 minutes = 1 degree, each minute is 1/60 of a degree. \n" ); document.write( "thus, 4' is 4/60 = 4/60 of a degree, = 0.067 of a degree. \n" ); document.write( "1 second = 1/3600 of a degree, so 40'' = 40/3600 of a degree = 0.0111. \n" ); document.write( "Thus, 63 degrees 4' 15'' = 63 + 0.067 + 0.011 = 63.078 degrees. \n" ); document.write( "The complement is this angle subtracted from 90, or 26.922. \n" ); document.write( "A good website for this is http://www.sunearthtools.com/dp/tools/conversion.php \n" ); document.write( "++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ \n" ); document.write( "For b, 90 - 82.73 = 7.27 degrees. \n" ); document.write( "Cleomenius. \n" ); document.write( " \n" ); document.write( " |
