The circumference of the circle with center O is divided into 12 equal arcs, marked the letters A through L as seen below. What is the number of degrees in the sum of the angles x and y?

We see nothing below that makes the situation clear for us. 
We have no way to know what the angles 'x' and 'y' are, or
even whether they're on the same planet as the circle.
