The 1 thing I do remember right away is that the intersecting radii form the central angle and that central angle is congruent to the measurement of ARC AB

So that means

Oh and that inscribed angle (ADB) would be equal to Half the arc length of AB

so

Also since AC and BC are tangents and intersect the circle at the same angle we know <A = <B

Those are also inscribed angles so they would be the same (half the length of the arc)

So it looks like angles A and B are also 50 degrees
