Using the Law of Cosines, we can find the missing side, M

 

M^2  = 220^2 + 143^2  - 2(220* 143) cos(75.7)

 

M = √ [ 220^2 + 143^2  - 2(220* 143) cos(75.7)]  ≈ 230.885 = 231  (rounded)

We can use the Law of Sines, here

 

AC / sin (71.6)  = 13 / sin ( 85.2)

 

AC  =  13sin (71.6) / sin (85.2)   = 12.378 cm =  12 cm  (rounded)
