Algebra.Com's Answer #73404 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The supplementary angle is 15 degrees less than 4 times the complementary angle. Find the angle. \n" ); document.write( "--------------- \n" ); document.write( "Let the angle be \"x\". \n" ); document.write( "The complement is \"90-x\" \n" ); document.write( "The supplement is \"180-x\" \n" ); document.write( "------------------ \n" ); document.write( "Equation: \n" ); document.write( "180-x = 4(90-x)-15 \n" ); document.write( "180-x = 360-4x-15 \n" ); document.write( "3x = 165 \n" ); document.write( "x = 55 degrees (this is \"the angle\") \n" ); document.write( "===================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
