Thank you so much!
Sorry for the inconvenience

I think this is the correct figure.  

Angle AOB has measure  and OB = 

Find OA.

Now you other tutors take it from there.

In reference to tutor Edwin's diagram, there's nothing in the instructions that mentions angle ABO must be 90 degrees (or that AB must be tangent to the smaller circle).

I agree fully with Math_Tutor2020 that there's nothing in the instructions that
mentions angle ABO must be 90 degrees (or that AB must be tangent to the smaller
circle).  It wasn't even given that the circles are concentric.

However, my gut sense tells me this was what the student intended. The student
probably had that diagram given.

If that wasn't what was intended, no harm done.

Triangle AOB is a 30-60-90 right triangle, so,'

you will find totally different from Edwin's plot, related to practically the same set of words.

It is not a tutor's job to guess or to restore a plot based on a given set of words.

In opposite, it is a  VISITOR's    to provide a right plot  (or at least a reference to a plot)
together with wording description.

Wrong. It's a tutor's job on this site to do whatever is necessary to help
bring the most struggling math students to this site. Not to act like a strict
math teacher, jumping on their backs because they make typos and don't copy
problems exactly like they're supposed to. They get enough yelling at them by
their teachers at school.
