Help solving trig equation
So I have to solve the equation where 0degrees<x<360degrees

My equation is tanx sinx - sinx = 0

I have a better idea on how to do these when it deals with ^2 so you can factor which seems to set up the answer easier. However, I have not done one like this and do not know where to start. Can someone help?

Thanks

Here are the first two steps:

$\displaystyle \sin (x) (\tan (x) - 1) = 0$

$\displaystyle \Rightarrow \sin(x) = 0$ or $\displaystyle \tan(x) - 1 = 0$.
