Trigonometry Identities - Sum to Product Identity True/False (Degrees)

Is this sum to product identity correct?

cos(300∘)+cos(30∘)=2sin((300∘+30∘)2)sin((300∘−30∘)2)\text{cos}{(300^{\circ})}+\text{cos}{(30^{\circ})} = 2 \text{sin}{( \frac{(300^{\circ} + 30^{\circ})}{2})} \text{sin}{( \frac{(300^{\circ} - 30^{\circ})}{2})}
