Solution: ∠APB=50° By degree measure theorem ∠AOB=2APB ∠APB=2*50°=100° since OA=OB [Radius of circle] Then ∠OAB=∠OBA [Angles opposite to equal sides] Let ∠OAB=x In OAb, by angle sum property ∠OAB+∠OBA+∠AOB=180° x+x+100°=180° 2x=180°-100° …
WebAnswer: Let O be the centre of two concentric circles C 1 and C 2 , whose radii are r 1 = 4 cm and r 2 = 5 cm. Now, we draw a chord AC of circle C 2 which is tangent to circle C 1 at B. Also, join OB, which is perpendicular to AC. So ∆ OBC is a right-angled triangle ∴ (OB) 2 + (BC) 2 = (OC) 2 (Pythagoras theorem) (4) 2 + (BC) 2 = (5) 2 WebIn figure, if ∠AOB = 125°, then ∠COD is equal to (a) 62.5° (b) 45° (c) 35° (d) 55° Solution: (d) We know that, the opposite sides of a quadrilateral circumscribing a circle subtend supplementary angles at the centre of the circle.
