I don't see a pic, but I assume that the arc in question is spanned by the chord......if so

 

60° arc   -   the radius  =   (1/2 chord length)/ sin (30)  =  5 / (1/2)  =  10

 

90° arc  -   the radius  =  (1/2 chord length) / sin (45)  =   5√2

 

180° arc  -   the radius  =  (1/2) chord length)  =   5
