Set x = the measure of the angle. \n" ); document.write( "The complement of x is 90-x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "complement = 30 plus twice the angle \n" ); document.write( "(90-x) = 30 + 2*x \n" ); document.write( "add x to each side \n" ); document.write( " 90 = 30 + 3x \n" ); document.write( "add -30 to each side \n" ); document.write( " 60 = 3x \n" ); document.write( "divide each side by 3 \n" ); document.write( " 20 = x \n" ); document.write( "Since the complement of x = (90-x) \n" ); document.write( "The complement is 90-x = 90-20 = 70\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
