:
\n" ); document.write( "Let x = the angle
\n" ); document.write( ":
\n" ); document.write( "The supplement: (180-x)
\n" ); document.write( "The complement: (90-x)
\n" ); document.write( ":
\n" ); document.write( "write what it says:
\n" ); document.write( "\"The measure of the supplement of an angle is 4 times the measure of its complement.\"
\n" ); document.write( "(180-x) = 4(90-x)
\n" ); document.write( ":
\n" ); document.write( "180 - x = 360 - 4x
\n" ); document.write( ":
\n" ); document.write( "-x +4x = 360 - 180
\n" ); document.write( ":
\n" ); document.write( "3x = 180
\n" ); document.write( "x =\"180%2F3\"
\n" ); document.write( "x = 60 is the angle
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the original equation:
\n" ); document.write( "(180-60) = 4(90-60)
\n" ); document.write( " 120 = 4(30); confirms our solution\r
