AC  is a diameter

 

arc ABC  =180

 

angle ABC measures (1/2)  of this arc  = 90

 

minor arc BC  =  2 * minor arc AB

 

So  let minor arc AB  = x

 

So   minor arc BC  = 2x

 

So minor  arc AB + minor arc BC  =180

 

            x              +  2x   =  180

 

3x  = 180

 

x  = 180/3   = 60

 

If minor arc AB  = 60   then  angle ACB  is  (1/2)  of this   =  30
