Which of the following is not a solution to the equation 4sin^2 X = 1
\n" ); document.write( "(a) 30
\n" ); document.write( "(b) 210
\n" ); document.write( "(c) 150
\n" ); document.write( "(d) 120
\n" ); document.write( "**
\n" ); document.write( "4sin^2x = 1
\n" ); document.write( "sin^x=1/4
\n" ); document.write( "sinx=1/2
\n" ); document.write( "x=30º and 150º in quadrants I and II where sin>0
\n" ); document.write( "(b) and (d) are not the solutions
\n" ); document.write( "
\n" );
