Question

Can someone help me answer theses questions please and thank you ill give medals

Answer 1

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

Answer 2

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

so

Answer 3

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
