document.write( "Answer: I believe the larger angle is 48 degrees. But that was by guessing.

Algebra.Com's Answer #266379 by checkley79(3341)![]() ![]() ![]() You can put this solution on YOUR website! 48 degrees CANNOT be the largest angle because. \n" ); document.write( "One of the angles MUST be greater than 60 degree. (3*60=180) \n" ); document.write( "----------------------------------------------------------- \n" ); document.write( "x+2x+(3x-24)=180 \n" ); document.write( "6x=180+24 \n" ); document.write( "6x=204 \n" ); document.write( "x=204/6 \n" ); document.write( "x=34 degrees is the smaller angle. \n" ); document.write( "3*34=68 degrees is the middle angle. \n" ); document.write( "3*34-24=102-24=78 degrees is the largest angle. \n" ); document.write( "Proof: \n" ); document.write( "34+68+78=180 \n" ); document.write( "180=180 \n" ); document.write( " \n" ); document.write( " |
