A regular hexagon is inscribed in a circle. If A and B are adjacent vertices of the pentagon and O is the center of the circle, what is the value of ∠OAB ? Choose the correct answer
A) 48 degrees B) 60 degrees C) 72 degrees D) 84 degrees E) 108 degrees
its a regular hexagon so divide the globe by 6.   = 360/6= 
<gadget id="calculator">360/6</gadget>
<output>60</output>
60   72 would be the angle at O.   Angles at A and B are equivalent, so   60 + 2x= 180   2x = 120   x = 60   Angles OAB and OBA will be 60 degrees each.   60 degrees
