Find three values theta, other than 15 degrees, such that sin theta=sin 15 degrees

Find three values of theta such that :

One way is to realize that the period of the sine function is 360 degrees; so any will work. (read: theta is 15 + 360n where n is an integer.)

So some possible values are etc...

Also, if theta works, 180-theta works as well. So we could include such as 165,475,etc...
