Algebra.Com's Answer #608370 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! I'm assuming you mean \"angle 1 and angle 2 add to 90 degrees\"\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so that would mean \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4x+5x = 90 \n" ); document.write( "9x = 90 \n" ); document.write( "9x/9 = 90/9 \n" ); document.write( "x = 10\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So angle 1 is 4x = 4*10 = 40 degrees \n" ); document.write( " |
