    Use the identity you have written below to get rid of either the sin^2 or the cos^2 term. That is, rearrange the identity and then subsitute. Then solve by rearranging and square rooting. Now you can find values for theta.

    If you divide both sides by cos^2(x) you will end up with tan^2(x) = 2 from the identity sin/cos = tan
