Algebra.Com's Answer #63776 by stanbon(75887) ![]() You can put this solution on YOUR website! The measure of an angle is 2/3 the measure of its supplement. Find the measure of the angle and its supplement. \n" ); document.write( "-------------- \n" ); document.write( "Let the angle be \"x\"; its supplement is \"180-x\". \n" ); document.write( "EQUATION: \n" ); document.write( "x = (2/3)(180-x) \n" ); document.write( "x = 120-(2/3)x \n" ); document.write( "(5/3)x = 120 \n" ); document.write( "x = 120(3/5) \n" ); document.write( "x = 72 degrees (one of the angles) \n" ); document.write( "180-x = 108 degrees (the other angle) \n" ); document.write( "============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
