K Verify the identity. secx-secx sin 2x = cos x Choose the

K Verify the identity. secx-secx sin 2x = cos x Choose the sequence of steps below that verifies the identity. OA. secx-secxsin 2x= secx (1- sin 2x) = 1 COS X = COS X COS X 2x O B. secx- secx sin 2x = secx (1- sin 2x)= 1 = COS X cos 2x = co C. secx- secxsin 2x = secx (sin 2x-1) 1 = COS = cos x COS X D. secx-secx sin 2x=1 - sin 2x= COS X
