Whаt is the meаsure оf аngle a? "The diagram shоws a circle centered at O, marked with a sоlid black dot. A horizontal chord extends across the circle through point O, representing the diameter and connecting two points on the left and right edges of the circle. From both ends of this diameter, two chords extend upward to a shared point on the upper-left part of the circle, forming a large triangle. A third chord connects this upper point to the bottom-left point on the circle, dividing the top angle of the triangle into two interior angles: the left angle is labeled ""d"", and the right-side angle is labeled 53 degrees. From the bottom-left point, two additional segments are drawn: a chord to the left endpoint of the diameter, and a radius to the center O. These segments form two smaller triangles. In the left triangle, angle ""a"" is formed between the horizontal diameter and the chord. In the right-side triangle, angle ""c"" is formed at the center between the diameter and the radius."
