Answer:
Correct answer: m∠A = 55°
Step-by-step explanation:
The quadrilateral ADCB around which the circle is described and whose sides are the chords of the circle has the characteristic that the sum of the opposite angles is 180°. According to this:
m∠A + m∠C = 180° => m∠A + 125° = 180° => m∠A = 180° - 125° = 55°
m∠A = 55°

AB=30
AC=22.5
8/15=12/x
x=22.5 (AC)
8/15=16/x
x=30 (AB)
