Find θ, 0° ≤ θ < 360°, given the following information.
\n" ); document.write( "cos θ = − squr(3)/2 and θ in QII
\n" ); document.write( "------
\n" ); document.write( "Sketch a 30-60 degree right triangle
\n" ); document.write( "Let the side opposite the 30 deg angle be 1
\n" ); document.write( "Then the hypotenuse is 2
\n" ); document.write( "And the base is sqrt(3)
\n" ); document.write( "----
\n" ); document.write( "So the cos(30) = sqrt(3)/2
\n" ); document.write( "------
\n" ); document.write( "For your problem the reference angle is arccos(sqrt(3)/2) = 30 degrees
\n" ); document.write( "----
\n" ); document.write( "In QII theta = 180+30 = 210 degrees
\n" ); document.write( "------------------
