Algebra.Com's Answer #508631 by Theo(13342)![]() ![]() You can put this solution on YOUR website! 30 right angles is equal to 30 * 90 = 2700 degrees. \n" ); document.write( "the sum of the angles of a regular polygon is given by the formula: \n" ); document.write( "(n-2) * (180) = sum of the interior angles of a polygon. \n" ); document.write( "this formula becomes: \n" ); document.write( "(n-2) * 180 = 2700 \n" ); document.write( "divide both sides of this equation by 180 to get: \n" ); document.write( "n-2 = 15 \n" ); document.write( "add 2 to both sides of this equation to get: \n" ); document.write( "n = 17 \n" ); document.write( "the number of sides is equal to 17. \n" ); document.write( "(17-2) * 180 = 15 * 180 = 2700. \n" ); document.write( "this confirms the solution is good. \n" ); document.write( " \n" ); document.write( " |
