measurement of angle A

I need help solving the triangle. I have been stuck on this for a while now.

 

a= 26.81

b= 21.82

c=18.02

 

Find the measurement of angle A

 

I know that it is 26.81​2​​ = (21.82)​2​​ + (18.02)​2​​ - 2 (21.82)(18.02)Cos A

 

For some reason I cant figure out how to properly get the right answer for this first part. it is not calculating properly.
