Algebra.Com's Answer #521817 by jim_thompson5910(35256) ![]() You can put this solution on YOUR website! I'm assuming this is a triangle.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If so, then let x be the third missing angle. All 3 angles of any triangle always add to 180 degrees (something to memorize). So,\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "63 + 26 + x = 180\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "89 + x = 180\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = 180 - 89\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = 91\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Therefore, the third missing angle is 91 degrees. \n" ); document.write( " |
