Seg AB and seg AD are the chords of the circle. C is a point on tangent of the circle at point A. If m(arc APB) 80° = and $\angle$BAD = 30°. Then find (i) $\angle$BAC (ii) m(arc BQD).
Secants containing chords RS and PQ of a circle intersect each other in point A in the exterior of a circle. If m(arc PCR) = 26° and m(arc QDS) = 48°, then find (1) $\angle$AQR (2) $\angle$SPQ (3) $\angle$RAQ.
Secant AC and secant AE intersects in point A. Points of intersections of the circle and secants are B and D respectively. If CB = 5, AB = 7, EA = 20. Determine ED - AD.
Chords AB and CD of a circle intersect in point Q in the interior of a circle of as shown in the figure. If m(arc AD) = 20°, and m(arc BC) = 36°, then find $\angle$BQC.
