Let the angle = x
\n" ); document.write( "It's complement is whatever angle added to it equals 90 degrees.
\n" ); document.write( "Let the complement = y
\n" ); document.write( "x+y=90
\n" ); document.write( "x is 40 less than two thirds its complement
\n" ); document.write( "x = 2/3y-40
\n" ); document.write( "plug that value for x into the equation
\n" ); document.write( "2/3y-40+y=90
\n" ); document.write( "multiply the whole equation by 3 to get rid of the fraction
\n" ); document.write( "3(2/3y-40+y=90) = 2y-120+3y=270
\n" ); document.write( "5y-120=270
\n" ); document.write( "5y=390
\n" ); document.write( "y=78\r
\n" ); document.write( "\n" ); document.write( "x+78=90
\n" ); document.write( "x=12\r
\n" ); document.write( "\n" ); document.write( "answer: the angle is 12 degrees\r
