"measuring 58°" . You mean "58m" or "58cm" something. 
By the way, is the radius not given, any additional info?

anonymous · Answer

50 degrees it doesn't have a radius given

anonymous · Answer

that's all the info there so idk

anonymous · Answer

You mean 58 degrees!
Its probably the angle of the arc JK inside the circle then

Is it?

anonymous · Answer

yeah J and K are an arc and the arc measures 58degrees

Fine, so

x = 180 - (90 + 29)
   =61 degree

So,  angle JKS = 2 x 61
                           =122 degrees
