$0\le \theta<360$ $4\sin \theta=\csc \theta$

2. anonymous

$\csc \theta = \dfrac{1}{\sin \theta}$ So you can multiply both sides by $$sin\theta$$ to get $$4\sin^2\theta = 1$$ Can you handle it now?

3. anonymous

Yep.

theta is 30,150 degrees

7. anonymous

Yup.

8. anonymous

By the way, it was 30,150,210,330 because$x ^{2}=\pm x$

9. anonymous

Yeah, you're right.
