    MHB Is \(\theta=360^\circ-\beta\) When \(\sin(\beta)=\frac{1}{3}\)?

    We've only stated 2 angles 90 and 270, is it either of those?

    wow I am lost there, but i would then solve this equation?

    from that I'm seeing 3 points marked, which is 3 solutions?

    Are you saying I should plot my 2 solutions into: $${0}^{0}\le\theta\le360^{0}$$

    Yes correct, I've made my substitutions to prove that question A is indeed true, however i am not sure how to start "B"

    MHB Is \(\theta=360^\circ-\beta\) When \(\sin(\beta)=\frac{1}{3}\)?

    I am aware that $\tan(x) = \frac{\sin(x)}{\cos(x)}$ and the other fundamental which is $1-\cos ^2(x)=\sin ^2(x)$ i just need some clarity on how its proven.x
