What is the angle of rotation counterclockwise about the spinner's center that maps label g to label b?

This is a very easy question to answer.  That's IF you see the picture
that shows the spinner and the locations of 'g' and 'B'.  Until you have
all of those pieces of information, it's impossible.

Idon’t know actually i’m in 5th grade and don’t know

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
