In acute triangle \(ABC\), \(\angle A = 68^\circ\). Let \(O\) be the circumcenter of triangle \(ABC\). Find \(\angle OBC\), in degrees.
BTW, circumcenter of a triangle is formed by the perpendicular bisectors of a triangle.
I hope this helps you further.
Haven't learned about these "peripheral angles," but thanks for the info.
