B is the right answer i think
Let's assume mzi is supposed to be m∠1.
Angle 1 and angle 2 are congruent, vertical angles. By the angle of intersecting chords theorem, each of them is the average of the two arcs,
m∠1 = m∠2 = (1/2)( 37° + 25° ) = 62° / 2 = 31°
Answer: 31°
They both saw the same amount because 6+3 = 9 and 3+6 = 9
