document.write( "Question 1037925: two angles are 72 degrees and 49 degrees they each appear twice in a pentagon what is the size of the 5th angle \n" ); document.write( "
Algebra.Com's Answer #652610 by Aldorozos(172)![]() ![]() ![]() You can put this solution on YOUR website! Please read this about a pentagon:\r \n" ); document.write( "\n" ); document.write( "http://www.mathsisfun.com/geometry/interior-angles-polygons.html \n" ); document.write( "The sum of the angles is 540\r \n" ); document.write( "\n" ); document.write( "72*2 + 49*2 + x = 540 \n" ); document.write( "Therefore 144 + 98 + x =540 If we solve this problem we get x=298 \n" ); document.write( "x can't be 298 since every angle of pentagon can't be greater than 180 degrees. My guess is that we don't have a pentagon that can have these angles. \n" ); document.write( " |
