Honestly? I have no idea.

I think you'll need to look up formulas related to tangent lines and arc lengths.  Have you a textbook or printed study guide?   If not, have you a study guide available online?
 
What I observe is that you have two lines tangent to the circle of unknown radius, and that these two lines meet at an angle of 70 degrees.  X represents the length of the arc of the circle that connects the two points of tangency.

I have an online study guide, I could try looking over it again, see if anything begins to click.

I've found a problem similar to it, the equation given is m<1 = ½ (m<arc AB, [in my case 70])

So.. M<1 = 1/2 (70), which would give me 35 correct?.. never mind that's not an option.

Now I'm even more confused.
