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!
