Algebra.Com's Answer #90310 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! sum of interior angles is 180(n-2) where n is the number of sides (and angles)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "let x=\"sides of first\", so 2x=\"sides of second\"\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(180(x-2))/(180(2x-2))=3/4\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "\"cross\" multiplying __ 4(180(x-2))=3(180(2x-2)) __ 720x-1440=1080x-1080\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "-360=360x __ x=-1\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "there appears to be something wrong with the problem __ check the parameters \n" ); document.write( " \n" ); document.write( " |
