how
the line from centre divides the angle between tangents equally so angle will be 30 degree n 30 degree now apply sin30°

2a is the answer.
draw a line joining the point of intersection of tangents and the center of the circle,it acts as the angle bisector.two triangles will be formed and the vertical angle of each triangle will be 30 degrees and by applying sin ratio of 30 degrees you get that the length of OP as 2a units
