hi qwertyzz,

Since we know $$\overline{CD}$$ and $$\overline{DA}$$ are congruent and $$\angle {ADC} \text{ is } 60^{\circ}$$, that means $$\triangle{ADC}$$ is an equilateral triangle. Because it's an equilateral triangle, that means all sides of $$\triangle{ADC}$$ are congruent. So, $$\overline{AC}$$ is also $$\boxed{17}$$.

I hope this helped you!

Let me know if you don't understand anything!
