Other answers:

take the square root of both sides costheta=2/3 and costhetha=-2/3
thetha=arccos(2/3) and thetha=arcsos(-2/3)
how did you get 3cos^2theta=2 if they aren't like terms so you can't combine them
oh I thought they were both raised to the second power my bad
i misread it
oh ok but do you understand it?
yes
give me just a sec
