Hello. Rounded to the nearest hundredth of a centimeter, 5.83 is correct for length AC.

Please show your work for solving angle ACD.

Angle ACD = 38.8º

Hi BOD. My answer for angle ACD is a few degrees smaller than yours. I'd try double-checking your calculations; maybe the issue is an arithmetic mistake, miscopied value or round-off error. (I'd carried four decimal places, in all my calculations.)
