Step-by-step explanation:

$\cos(a) + 2 \cos(a + 240)$

$\cos(a) + 2 \cos(a) \cos(240) - \sin(a) \sin(240)$

$\cos(a) + 2( - \frac{ \cos(a) }{2} + \frac{ \sqrt{3} }{2} \sin(a) )$

$\cos(a) - \cos(a) + \sqrt{3} \sin(a)$

$\sqrt{3} \sin(a)$

If you graph the new identity, and the og identiy, they will be conciding graphs, so they are the same identity.
