Trigonometry Pearson New International Edition - Then resulting equation will be: $$\cos(\theta-60^\circ)=\frac\sin(\theta)$$ $$\cos(60^\circ) \cos\theta \sin(60^\circ) \sin\theta=\frac\sin\theta$$ $$ 2\cos(60^\circ) \cos\theta 2\sin(60^\circ) \sin\theta=\sin\theta.$$ You can then substitute the values of $\sin(60^\circ)$ and $\cos(60^\circ)$ into the equation, and then divide both sides by $\sin\theta$.
