x = angle
\n" ); document.write( "Since a complement of angle x means that the complement plus the angle add up to 90 degrees, the expression of the complement would be 90 - x
\n" ); document.write( "\"angle...is half of its own complement\"
\n" ); document.write( "angle = $\"1%2F2\"$ (complement)
\n" ); document.write( " $\"x+=+%281%2F2%29%2890+-+x%29\"$
\n" ); document.write( "Distribute the one-half into the 90 and -x: $\"x+=+45+-+x%2F2\"$
\n" ); document.write( "Multiply both sides by 2 to clear fraction: $\"2x+=+90+-+x\"$
\n" ); document.write( "Add x to both sides: $\"3x+=+90\"$
\n" ); document.write( "Divide both sides by 3: $\"x+=+30\"$
\n" ); document.write( "***THEREFORE, THE ANGLE THAT IS HALF OF ITS OWN COMPLEMENT IS (A) 30 \n" ); document.write( "
