Theta ($ \theta $) is a symbol used to denote the unknown measure of an angle.

It is used mostly in displaying the trigonometric ratios of sine, cosine, and tangent. For example: 

$ \sin\theta=\frac{\mbox{opp}}{\mbox{hyp}} $
$ \cos\theta=\frac{\mbox{adj}}{\mbox{hyp}} $
$ \tan\theta=\frac{\mbox{opp}}{\mbox{adj}} $
